wayland: Error check before using cached wl_display

Browse source 
A planar(or some other) buffer allocation may fail on the driver, then
the wayland connection becomes invalid, not able to send request or
receive any event. So we need to set up a new wayland connection if
there's an error detected on the cached wl_display.
