[SCSI] libfc: use ADISC to verify rport login state
When rport_login is called on an rport that is already thought
to be logged in, use ADISC. If that fails, redo PLOGI.
This is less disruptive after fabric changes that don't affect
the state of the target.
Implement the sending of ADISC via fc_els_fill.
Add ADISC state to the rport state machine. This is entered from READY
and returns to READY after successful completion. If it fails, the rport
is either logged off and deleted or re-does PLOGI.
