scsi: qla2xxx: Fix a locking imbalance in qlt_24xx_handle_els()
Ensure that upon return the tgt->ha->tgt.sess_lock spin lock is unlocked
no matter which code path is taken through this function. This was
detected by sparse.
Fixes: 82abdcaf3ede ("scsi: qla2xxx: Allow target mode to accept PRLI in dual mode")
