Ray Strode acd50508dc wayland: return from toplevel commit early if no new buffer
meta_wayland_surface_toplevel_commit has a lot of logic to handle
a new buffer getting attached as part of the commit.  None of
that code needs to run if there is no new buffer attached.

This commit short-circuits that case.
