[PATCH v10 02/12] x86/mm: remove pv_ops.mmu.tlb_remove_table call

[Rik van Riel <riel@surriel.com>]

Every pv_ops.mmu.tlb_remove_table call ends up calling tlb_remove_table.

Get rid of the indirection by simply calling tlb_remove_table directly,
and not going through the paravirt function pointers.
