scsi: qla2xxx: edif: Reduce connection thrash
[ Upstream commit
91f6f5fbe87ba834133fcc61d34881cb8ec9e518 ]
On ipsec start by remote port, target port may use RSCN to trigger
initiator to relogin. If driver is already in the process of a relogin,
then ignore the RSCN and allow the current relogin to continue. This
reduces thrashing of the connection.
