socket: allow wait=false for client socket
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. Deprecate usage of 'wait' with client sockets. Fixes: 767abe7f49e8be14d29da5db3527817b5d696a52 Cc: Daniel P.
