Commit 767abe7 ("chardev: forbid 'wait' option with client sockets")
is a bit too strict. Current libvirt always set wait=false, and will
thus fail to add client chardev.
Make the code more permissive, allowing wait=false with client socket
chardevs.

NB, it should also update qemu-deprecated.texi

It applies to command line syntax too, so I would just generalize that
a little to
"Character devices creating sockets in client mode should not
specify the 'wait' field, which is only applicable to sockets
in server mode"
