vu_common: Pass explicit frame length to vu_flush()
Currently vu_flush() derives the frame size from the iov, but in
preparation for iov arrays that may be larger than the actual frame,
pass the total length (including vnet header) explicitly so that only
the relevant portion is reported to the virtqueue.
Ensure a minimum frame size of ETH_ZLEN + VNET_HLEN to handle short
frames. All elements are still flushed to avoid descriptor leaks,
but trailing elements beyond frame_len will report a zero length.
