scsi: qla2xxx: Fix a couple of misdocumented functions

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/qla2xxx/qla_target.c:6476: warning: expecting prototype for qla_tgt_lport_register(). Prototype was for qlt_lport_register() instead
 drivers/scsi/qla2xxx/qla_target.c:6546: warning: expecting prototype for qla_tgt_lport_deregister(). Prototype was for qlt_lport_deregister() instead
