Liu Shixin 38753f1ada mm/memory-failure: fix an incorrect use of tail pages ...

When backport commit c79c5a0a00a9 to 5.10-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: 70168fdc74 ("mm/memory-failure: check the mapcount of the precise page")
