mm: memory-failure: remove unneeded PageHuge() check 

Patch series "A few fixup and cleanup patches for memory-failure", v2.

This series contains a few fixup patches to fix inaccurate mf_stats, fix
race window when trying to get hugetlb folio and so on.  Also there is
minor cleanup for comments and codestyle.  More details can be found in
the respective changelogs.


This patch (of 8):

PageHuge() check in me_huge_page() is just for potential problems.  Remove
it as it's actually dead code and won't catch anything.
