Now, I set it up so that if you don't use delayed_rmap, the
tlb_flush_rmaps() function ends up being an empty inline function, and
as such the compiler should already have done this for you - including
optimizing out the test that then doesn't even matter.
But this patch shouldn't *matter*, but it also isn't wrong, so..
