Paolo Abeni 3c4cea8fa7 vhost_net: fix OoB on sendmsg() failure. 
If the sendmsg() call in vhost_tx_batch() fails, both the 'batched_xdp'
and 'done_idx' indexes are left unchanged. If such failure happens
when batched_xdp == VHOST_NET_BATCH, the next call to
vhost_net_build_xdp() will access and write memory outside the xdp
buffers area.

Since sendmsg() can only error with EBADFD, this change addresses the
issue explicitly freeing the XDP buffers batch on error.

Fixes: 0a0be13b8f ("vhost_net: batch submitting XDP buffers to underlayer sockets")
