Subject: [PATCH] MIPS/thp: Fix update_mmu_cache() cache call

As per recent upstream commit:

  b113da65785d mm: Add and use update_mmu_cache_pmd() in transparent huge page code.

The call in do_huge_pmd_prot_none() needs to call update_mmu_cache_pmd()
as well.

This resolves a MIPS build error triggered on linux-next.
