[PATCH] qemu: do not set wait:false for client sockets

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

Qemu commit 767abe7 ("chardev: forbid 'wait' option with client
sockets") effectively deprecates usage of "wait" with client sockets
starting with qemu 4.0, and earlier versions ignored the value.
