wayland/surface: Move committed buffer size check out of if (buffer)

Browse Source 
A surface commit may change the buffer scale but not attach a new
buffer. In that case, the size of the previously attached buffer needs
to be consistent with the new buffer scale.

Fixes: 7649e2f3ab ("wayland/surface: Move buffer size check to meta_wayland_surface_commit")
