hugetlb: pass head page to remove_hugetlb_page()

mainline inclusion
from mainline-v5.13-rc5
commit 0c5da357
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9SZXR
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0c5da35723a961d8c02ea516da2bcfeb007d7d2c

-------------------------------------------

When memory_failure() or soft_offline_page() is called on a tail page of
some hugetlb page, "BUG: unable to handle page fault" error can be
triggered.

remove_hugetlb_page() dereferences page->lru, so it's assumed that the
page points to a head page, but one of the caller,
dissolve_free_huge_page(), provides remove_hugetlb_page() with 'page'
which could be a tail page.  So pass 'head' to it, instead.
