Jonas Ådahl 75ec27966d wayland/buffer: Only query Wayland EGL buffer if display bound
It's not allowed to call eglQueryWaylandBuffer() if the call to
eglBindWaylandDisplay() failed, and will result in an assert being hit
in mesa if called.

Avoid that by keeping track whether we succeeded to bind, and only
attempt to realize a legacy EGL wl_buffer if binding succeeded.
