util/vhost-user-server: fix memory leak in vu_message_read()
...
fds[] is leaked when qio_channel_readv_full() fails.
Use vmsg->fds[] instead of keeping a local fds[] array. Then we can
reuse goto fail to clean up fds. vmsg->fd_num must be zeroed before the
loop to make this safe.

util/vhost-user-server: drop unnecessary watch deletion
...
Explicitly deleting watches is not necessary since libvhost-user calls
remove_watch() during vu_deinit(). Add an assertion to check this
though.
