Silence compile warning due to unaligned memory access.

qla_edif.c:713:45: warning: taking address of packed member 'u' of class or
   structure 'auth_complete_cmd' may result in an unaligned pointer value
   [-Waddress-of-packed-member]
    fcport = qla2x00_find_fcport_by_pid(vha, &appplogiok.u.d_id);
