[PATCH trivial] tcp_vu, udp_vu: Fix comment headers for header length functions

[Laurent Vivier <lvivier@redhat.com>]

The comment headers for tcp_vu_hdrlen() and udp_vu_hdrlen() described
the return value as "the size of the header in level 2 frame", but
these functions also include the virtio net header, which is not part
of the L2 frame.
