nat: Fix memory leak... in MGCP forwarding
The code needs to be refactored but this is fixing the leak for
now. We used to forward everything to the BSC but now we handle
the DLCX locally and this means we need to clear the patched
message. We should refactor it to not generate the patched msg
until a lot later.
