x86/mm/cpa: Move flush_tlb_all()
There is an atom errata, where we do a local TLB invalidate right
before we return and then do a global TLB invalidate.
Move the global invalidate up a little bit and avoid the local
invalidate entirely.
This does put the global invalidate under pgd_lock, but that shouldn't
matter.
