Huang Ying 7dcd620416 migrate_pages_batch: fix statistics for longterm pin retry ...

commit 851ae64246 upstream.

In commit fd4a7ac329 ("mm: migrate: try again if THP split is failed due
to page refcnt"), if the THP splitting fails due to page reference count,
we will retry to improve migration successful rate.  But the failed
splitting is counted as migration failure and migration retry, which will
cause duplicated failure counting.  So, in this patch, this is fixed via
undoing the failure counting if we decide to retry.  The patch is tested
via failure injection.
