Revert "MIPS: add PMD table accounting into MIPS'pmd_alloc_one"



This reverts commit 002d8b39 which is
commit ed914d48b6a1040d1039d371b56273d422c0081e upstream.

Commit b2b29d6d011944 (mm: account PMD tables like PTE tables) is
introduced between v5.9 and v5.10, so this fix (commit 002d8b39)
should NOT apply to any pre-5.10 branch.
