Revert "mm/memory-failure.c: fix race with changing page compound again"

Browse Source 
Reverts commit 888af2701d ("mm/memory-failure.c: fix race with changing
page compound again") because now we fetch the page refcount under
hugetlb_lock in try_memory_failure_hugetlb() so that the race check is no
longer necessary.
