scsi-disk: release AioContext in unaligned WRITE SAME case
scsi_write_same_complete() can retry the write if the request was
unaligned. Make sure to release the AioContext when that code path is
taken!
This patch fixes a hang when QEMU terminates after an unaligned WRITE
SAME request has been processed with dataplane. The hang occurs because
iothread_stop_all() cannot acquire the AioContext lock that was leaked
by the IOThread in scsi_write_same_complete().
Fixes: b9e413dd37 ("block: explicitly acquire aiocontext in aio callbacks that need it").
