sh/tlb: Fix PGTABLE_LEVELS > 2 

[ Upstream commit c7bcbc8ab9 ]

Geert reported that his SH7722-based Migo-R board failed to boot after
commit:

  c5b27a889d ("sh/tlb: Convert SH to generic mmu_gather")

That commit fell victim to copying the wrong pattern --
__pmd_free_tlb() used to be implemented with pmd_free().

Fixes: c5b27a889d ("sh/tlb: Convert SH to generic mmu_gather")
