[PATCH] remove weird pmd cast

I don't know what this is trying to do.  It might be some kind of artifact
from when get_pgd_slow() was removed.

The expanded expression with __pa() ends up looking something like this:

	(unsigned long)(u64)(u32)pmd-PAGE_OFFSET

and that is just nutty because pmd is a pointer now, anyway.

Attached patch removes the casts.
