Liu Shixin 7f75e937ec mm/memory-failure: fix an incorrect use of tail pages
When backport commit c79c5a0a00a9 to 5.4-stable, there is a mistake change.
The head page instead of tail page should be passed to try_to_unmap(),
otherwise unmap will failed as follows.

 Memory failure: 0x121c10: failed to unmap page (mapcount=1)
 Memory failure: 0x121c10: recovery action for unmapping failed page: Ignored

Fixes: 85015a96bc24 ("mm/memory-failure: check the mapcount of the precise page")
