[SCSI] iscsi class: regression - fix races with state manipulation and blocking/unblocking
For qla4xxx, we could be starting a session, but some error (network, target, IO from a device that got started, etc) could cause the session to fail and curring the block/unblock and state manipulation could race with each other. This patch just has those operations done in the single threaded iscsi eh work queue, so that way they are serialized.
