Since "fw-sbp2: fix I/O errors during reconnect", a Scsi_Host will be
blocked as soon as a command failed due to bus generation change. Now
we also block it when fw-core signalled a bus reset via sbp2_update.
This will avoid some command failures and retries (but not all because
commands are injected from tasklet context while sbp2_update runs from
workqueue thread context).
