of duplicating the same code many times, introduce 2 helpers:
- sd_cmd_to_sendingdata() on the I/O line setup the data to

- sd_generic_read_byte() on the DAT lines to fetch the data.

A malicious or buggy guest may generated buffered ioreqs faster than
QEMU can process them in handle_buffered_iopage(). The result is a
livelock - QEMU continuously processes ioreqs on the main thread without
iterating through the main loop which prevents handling other events,
processing timers, etc. Without QEMU handling other events, it often
results in the guest becoming unsable and makes it difficult to stop the
source of buffered ioreqs.
To avoid this, if we process a full page of buffered ioreqs, stop and
reschedule an immediate timer to continue processing them. This lets
QEMU go back to the main loop and catch up.

vfio_container_destroy() clears the resources allocated
