sgsn: delay f_gmm_attach() by 50ms
Packets sent by f_gmm_attach() might take too long via layers to reach
the SGSN. The GMM_ATTACH_COMPL in f_gmm_attach() took soo long,
that it arrived after packets, which has been sent after calling f_gmm_attach().
This behaviour was found in TC hlr_location_cancel_request_update().
