udp_vu: Allow virtqueue elements with multiple iovec entries
The previous code assumed a 1:1 mapping between virtqueue elements and
iovec entries (enforced by an assert). Drop that assumption to allow
elements that span multiple iovecs: track elem_used separately by
walking the element list against the iov count returned after padding.
This also fixes vu_queue_rewind() and vu_flush() to use the element
count rather than the iov count.
Use iov_tail_clone() in udp_vu_sock_recv() to handle header offset,
replacing the manual base/len adjustment and restore pattern.
