[PATCH] mm: page-flags: fix build failure due to missing parameter for HasHWPoisoned flag

[Yang Shi <shy828301@gmail.com>]

The below build failure when !CONFIG_MEMORY_FAILURE was reported for
v5.16 merge window:

The commit d389a4a81155 ("mm: Add folio flag manipulation functions")
changed the definition of PAGEFLAG macros, this caused the build failure
for HasHWPoisoned flag.  The new flag was introduced by commit
eac96c3efdb5 ("mm: filemap: check if THP has hwpoisoned subpage for PMD
page fault") in v5.15-rc7.  But the folio series pull request was
prepared before v5.15, so this new flag was missed.
