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.

Fixes: 767abe7f49e8be14d29da5db3527817b5d696a52

NB, it should also update qemu-deprecated.texi
