When a port sends PLOGI, discovery state should be changed to login
pending, otherwise RELOGIN_NEEDED bit is set in
qla24xx_handle_plogi_done_event(). RELOGIN_NEEDED triggers another
PLOGI, and it never goes out of the loop until login timer expires.

Fixes: 8b5292bcfcacf ("scsi: qla2xxx: Fix Relogin to prevent modifying scan_state flag")
