sgsn: Fix crash using new libgtp cb_recovery2 API

When PDP CTX CREATE ACK is received with an increased RestartCtr, cb_recovery2
is called first, which will dettach ggsn from al pdp ctx (free the
pdp_t). But when giving control back from the ctrl, libgtp still uses
that freed ctx and sends it back to osmo-sgsn through cb_conf().

As specs state in any case that we need to handle the message containing
the increased RestartCtr as valid, we then need to avoid freeing the pdp
ctx and leave handling for later in cb_conf.

Depends: osmo-ggsn (libgtp) Change-Id I53e92298f2f6b84d662a3300d922e8c2ccb178bc.
