tcp: unify payload and flags l2 frames array
In order to reduce static memory and code footprint, we merge
the array for l2 flag frames into the one for payload frames.
This change also ensures that no flag message will be sent out
over the l2 media bypassing already queued payload messages.
Performance measurements with iperf3, where we force all
traffic via the tap queue, show no significant difference:
