Subject: mm/memory-failure.c: minor cleanup for HWPoisonHandlable

Patch series "A few fixup and cleanup patches for memory failure", v2.

This series contains a patch to clean up the HWPoisonHandlable and another
one to dissolve truncated hugetlb page.  More details can be found in the
respective changelogs.


This patch (of 2):

The local variable movable can be removed by returning true directly. Also
fix typo 'mirgate'. No functional change intended.
