scsi: qla2xxx: Fix unintended Logout

[ Upstream commit cb97f2c2e8d9f8c71ddbf04ad57e163ee6d86474 ]

During normal IO, FW can return IO with 'port unavailble' status.  Driver
would send a LOGO to remote port for session resync.  On an off chance, a
PLOGI could arrive before sending the LOGO.  This patch will skip sendiing
LOGO if a PLOGI just came in.
