From: Quinn Tran <qutran@xxxxxxxxxxx>
On fast cable pull, where driver is unable to detect device
has disappeared and came back based on switch info, qla2xxx
would not re-login while remote port has already invalidate
the session. This cause IO timeout. This patch would relogin
to remote device for RSCN affected port.
