sgsn: Create a copy of the msgb for later usage

When needing to do an asynchronous DNS query we need
to keep the TLV data around. So create a wrapper that
takes a copy of it and frees it after the call. I can
change the code to add an out parameter to decide if
the msgb should be freed or not.

Pick network failure in case the msgb could not be
cloned in the hope the MS will retry then.
