From: Hannes Reinecke <hare@xxxxxxxx>
When an RSCN gets delayed (or not being sent at all) the transport
class will detect an error, EH kicks in, and eventually will be
setting the device to offline.
If we receive an RSCN after that the device will stay in 'offline'.
This patch allows for an 'offline' to 'blocked' transition, thereby
allowing the device to become active again.
