osmo-ggsn: print requested / actual APN in PDP info

An actual APN can be different from the one that was requested by
user, e.g. when 'default-apn' VTY parameter is used. The one that
was requested is already being stored in the PDP context state.
Let's also store a chosen APN in create_context_ind().
