libgtp: Define retransmit QUEUE_SIZE relative to PDP_MAX (increase)

QUEUE_SIZE holds the number of pending transmitted messages
which can be handled concurrently.
Current value was 1024, same as PDP contexts (PDP_MAX). However, that
seems to be a quite low amount, which can be filled under certain
conditions, for instance if recovery procedure is triggered on the GSN
which is running full (around PDP_MAX pdp contexts created).
In this scenario, the GSN would need to send around PDP_MAX concurrent
messages (DeletePDPContextReq), which means the queue would very likely
end up being full.
Hence, let's define QUEUE_SIZE based on PDP_MAX, and set it to twice the
size to make sure it won't be filled in extreme conditions.
