Jonas Ådahl cf6c11cfaa wayland: Only set surface buffer scale when supported
Although very unlikely, the wl_compositor version might not support
wl_surface.set_buffer_scale while the wl_output emits a wl_output.scale
that is larger than 1. So for correctness, bail on changing the buffer
scale if we won't be able to set it later.
