Michel Dänzer 51ee6e5ceb xwayland: Check window pixmap in xwl_present_check_flip2 
We can only flip if the window pixmap matches that of the toplevel
window. Doing so regardless could cause the toplevel window pixmap to
get destroyed while it was still referenced by the window, resulting in
use-after-free and likely a crash.
