fix build: gprs_ra_id_by_bts(): ensure to init all values
After recent libosmocore commit "implement support for 3-digit MNC with leading zeros" c4fce1425e19d604c199c895e227dc2519110456 Id2240f7f518494c9df6c8bda52c0d5092f90f221, struct gprs_ra_id has a new member, namely mnc_3_digits. In gprs_ra_id_by_bts(), this new member is now not initialized and may end up having an arbitrary value, which then may amount to mnc_3_digits == true. Hence the resulting BCD representation of the MCC-MNC may inadvertently and randomly indicate a leading zero on the MNC. Use a struct assignment so that all members are guaranteed to be set, and so that mnc_3_digits will be zero in all cases. Since above libosmocore commit, nanobts_omlattr_test fails "randomly", fixed by this patch. Change-Id: I872ae3b2b0a0cd8f932f3a5fbc77c0dbfcb28bbf
