Change mfi_mgmt() to take a mfi_ccb and scsipi_xfer as argument, as

mfi_scsi_io does. Do not tsleep in mfi_mgmt waiting for completion;
let the caller handle it. If mfi_mgmt() is called with a non-NULL scsipi_xfer
have mfi_mgmt_done() wake it up, else wake up the mfi_ccb.
mfi_poll()/mfi_post() is up to the caller.

mfi_scsipi_request(): handle SCSI_SYNCHRONIZE_CACHE_10 as we do for other
commmands: have mfi_mgmt() fill in the ccb, queue of poll the ccb and
return.

Introduce mfi_mgmt_internal() which behaves like mfi_mgmt() did (tsleep
waiting for completion). Use it for internal and ioctl management
requests.

Fix kern/39297 from Greg Oster (mfi calls tsleep() from mfi_intr()),
tested by Mark Davies.
