tcp_vu: vu_pad() expects l2 length
tcp_vu_hdrlen() returns a length that includes VNET_HLEN (the virtio
net header), but vu_pad() expects the Layer-2 frame length, which
should not include the virtio header. Passing the inflated length
means short frames aren't padded to the minimum 60-byte Ethernet
frame size (ETH_ZLEN).
Subtract VNET_HLEN from hdrlen when computing the l2 length passed
to vu_pad() in both tcp_vu_send_flag() and tcp_vu_data_from_sock().
Fixes: 0cb8f9003654 ("tcp, udp: Pad batched frames for vhost-user modes to 60 bytes (802.3 minimum)")
