gprs_gmm: segfault: gracefully handle failure to alloc context
This counter allocation error I hit uncovers a segfault when allocating an MM context fails in the GSM_MI_TYPE_TMSI case: DRANAP <001a> ../../../src/osmo-iuh/src/iu_client.c:509 handle_co_initial(dir=1, proc=19) DRANAP <001a> ../../../src/osmo-iuh/src/iu_client.c:229 RNC 23: new LAC 24358 RAC 22 DMM <0002> ../../../../src/osmo-sgsn/src/gprs/gprs_gmm.c:1271 MM(---/ffffffff) -> GMM ATTACH REQUEST MI(3427325924) type="GPRS attach" DLGLOBAL <001d> ../../../src/libosmocore/src/rate_ctr.c:195 counter group 'sgsn:mmctx' already exists for index 0 DMM <0002> ../../../../src/osmo-sgsn/src/gprs/gprs_sgsn.c:272 MM(/00000000) Cannot allocate counter group Program received signal SIGSEGV, Segmentation fault. gsm48_rx_gmm_att_req (llme=0x0, msg=0x555555886950, ctx=0x0) at ../../../../src/osmo-sgsn/src/gprs/gprs_gmm.c:1375 1375 ctx->p_tmsi = tmsi; Fix it with a bit of code already present for the GSM_MI_TYPE_IMSI case just above the segfault.
