Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report
errors from scsi_bus_legacy_add_drive() with error_report() in
addition to returning them. That's inappropriate.
Two kinds of callers:
1. realize methods (devices "esp", "virtio-scsi-device" and
"spapr-vscsi")
The error object gets passed up the call chain until it gets
reported again and freed.
Example:
$ qemu-system-arm -M virt -S -display none \
> -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \
> -device nec-usb-xhci -device usb-storage,drive=foo \
> -device virtio-scsi-pci
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use
qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed
qemu-system-arm: -device virtio-scsi-pci: Device initialization failed
qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized
The second message in this error cascade comes from
scsi_bus_legacy_handle_cmdline(). The error object then gets
passed up to the qdev_init() called from
virtio_scsi_pci_init_pci(), which reports it again.
2. init methods (devices "am53c974", "dc390", "lsi53c895a",
"lsi53c810", "megasas", "megasas-gen2")
init methods need to report their errors with qerror_report().
These don't. The inappropriate error_report() papers over the bug.
error_report() isn't the same as qerror_report() in QMP context,
but this can't actually happen: QMP can still only hot-plug, and
callers call scsi_bus_legacy_handle_cmdline() only on cold-plug.
Except for sysbus_esp_realize(), but that can't be hot-plugged at
all, as far as I can tell.
Fix the init methods and drop the inappropriate error_report() in
scsi_bus_legacy_handle_cmdline().

A linux guest will be issuing messages:

[ 32.126348] DC390: DataIn_0: DMA State: 0
and the HBA will fail to work properly.
Reason is the emulation is not setting the 'DMA transfer done'
status correctly.

After previous Peter patch, they are redundant. This way we don't
assign them except when needed. Once there, there were lots of case
where the ".fields" indentation was wrong:
.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:
.fields = (VMStateField[]){
The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

pci_set_irq and the other pci irq wrappers use
PCI_INTERRUPT_PIN config register to compute device

An irq is allocated using pci_allocate_irq wrapper
only if is needed by non pci devices.
Removed irq related fields from state if not used anymore.
