We can race where iscsi_session_recovery_timedout has woken up the error
handler thread and it's now setting the devices to offline, and
session_recovery_timedout's call to scsi_target_unblock is also trying to
set the device's state to transport-offline. We can then get a mix of
states.

For the case where we can't relogin we want the devices to be in
transport-offline so when we have repaired the connection
__iscsi_unblock_session can set the state back to running. So this patch
has us set the device state then call into libiscsi to wake up the error
handler.
