libgtp: Use gtp_cause_successful() instead of GTPCAUSE_ACC_REQ

In some cases the phone requests a PDP context type that isn't available
no the PGW/GGSN, e.g. phone requests a combined IPv4/v6 context, but
only IPv4 is supported.

In that case the GGSN can send a Create PDP Context Response with cause
"New PDP type due to network preference" or "New PDP type due to single
address bearer only". libgtp should continue handling these cause values
like the "Request Accepted" cause. Use the new gtp_cause_successful()
function for that.
