sh/tlb: Fix PGTABLE_LEVELS > 2
Geert reported that his SH7722-based Migo-R board failed to boot after
commit:
c5b27a889da9 ("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: c5b27a889da9 ("sh/tlb: Convert SH to generic mmu_gather")
