mm/selftests: fix incorrect pointer being passed to mark_range()

Patch series "selftests/mm: Fix false positives and skip unsupported
tests", v4.

This patch series addresses false positives in the generic mm selftests
and skips tests that cannot run correctly due to missing features or
system limitations.

This patch (of 7):

In main(), the high address is stored in hptr, but for mark_range(), the
address passed is ptr, not hptr.  Fixed this by changing ptr[i] to hptr[i]
in mark_range() function call.
