mmu_notifiers: remove leftover stub macros

Commit ec8832d007cb ("mmu_notifiers: don't invalidate secondary TLBs as
part of mmu_notifier_invalidate_range_end()") removed the main definitions
of {ptep,pmdp_huge,pudp_huge}_clear_flush_notify; just their
!CONFIG_MMU_NOTIFIER stubs are left behind, remove them.
