mlx4: xdp: Reserve headroom for receiving packet when XDP prog is active
Reserve XDP_PACKET_HEADROOM for packet and enable bpf_xdp_adjust_head()
support. This patch only affects the code path when XDP is active.
After testing, the tx_dropped counter is incremented if the xdp_prog sends
more than wire MTU.
