scsi_transport_srp.c will call scsi_target_block() repeatedly

So allow the idempotent state transition BLOCK -> BLOCK to avoid
a warning here.
That really doesn't sound like a good idea. Block and unblock should
be matched pairs and since you don't have a running->running transition
allowed this implies that srp calls block many times but unblock only
once. It really sounds like srp needs fixing.
That was what I was planning first, but then SRP has a weird mix of
states, calling scsi_target_block()/scsi_target_unblock() on all sorts
of places.
Bart?
