Peter Zijlstra ccde85ba00 mm, locking: Fix up flush_tlb_pending() related merge in do_huge_pmd_numa_page() 
Merge commit:

  040cca3ab2 ("Merge branch 'linus' into locking/core, to resolve conflicts")

overlooked the fact that do_huge_pmd_numa_page() now does two TLB
flushes. Commit:

  8b1b436dd1 ("mm, locking: Rework {set,clear,mm}_tlb_flush_pending()")

and commit:

  a9b802500e ("Revert "mm: numa: defer TLB flush for THP migration as long as possible"")

Both moved the TLB flush around but slightly different, the end result
being that what was one became two.

Clean this up.
