tsnep: Prepare RX buffer for XDP support
Always reserve XDP_PACKET_HEADROOM in front of RX buffer. Similar DMA
direction is always set to DMA_BIDIRECTIONAL. This eliminates the need
for RX queue reconfiguration during BPF program setup. The RX queue is
always prepared for XDP.
No negative impact of DMA_BIDIRECTIONAL was measured.
