[RFC PATCH v2 1/4] virtio/vsock: fix 'rx_bytes'/'fwd_cnt' calculation

[Arseniy Krasnov]

Substraction of 'skb->len' is redundant here: 'skb_headroom()' is delta
between 'data' and 'head' pointers, e.g. it is number of bytes returned
to user (of course accounting size of header). 'skb->len' is number of
bytes rest in buffer.

Fixes: 71dc9ec9ac7d ("virtio/vsock: replace virtio_vsock_pkt with sk_buff")
