gbproxy: Only patch what has been configured
Currently when patching is basically enabled P-TMSI and TLLI gets
patched even when P-TMSI patching is not enabled. Albeit the result
is correct in this case (the same value is re-written), the counter
shows unexpected results.
This patch adds configuration checks for P-TMSI and TLLI patching. It
also reorders the code of gbproxy_patch_raid to return early if there
is nothing to patch.
