xwayland/present: Check allow_commits in xwl_present_flip

Browse Source 
We're not supposed to call wl_surface_commit while
xwl_window->allow_commits is false. Bailing results in falling back to
a copy.

Noticed by inspection while looking into an issue which turned out to be
due to something else.
