chardev: forbid 'wait' option with client sockets
The 'wait'/'nowait' parameter is used to tell server sockets whether to block until a client is accepted during initialization. Client chardevs have always silently ignored this option. Various tests were mistakenly passing this option for their client chardevs. Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Daniel P.
