scst_local: Avoid deadlock during module removal with kernel 3.6
...
Since kernel 3.6 a SYNCHRONIZE CACHE command is sent to SCSI disks
during the scsi_remove_host() call. That command is sent after command
processing has been suspended in SCST and hence causes a deadlock.
Avoid this deadlock by failing all commands issued after
scst_unregister_target() has been invoked.
The output of echo w >/proc/sysrq-trigger just after module removal of
scst_local started is as follows:
