fixup: apply mnc3 change also in ipaccess/network_listen.c

Preceding commit I38ac98a4d25159cfd4f686efbfbaf8f00625a6d8 changed the
ipac_bcch_info.cgi type to osmo_cell_global_id, but did not carry out
corresponding changes in ipaccess/network_listen.c.

The reason this was not caught is that recent commit
I68286d26e2014048b054f39ef29c35fef420cc97 adding the new gscon FSM actually
disables ipaccess-config in the build.

Fix the build, given that ipaccess-config were re-enabled.
