[PATCH] mshv: Use PMD_ORDER instead of HPAGE_PMD_ORDER when processing regions

[Stanislav Kinsburskii]

Fix page order determination logic when CONFIG_PGTABLE_HAS_HUGE_LEAVES
is undefined, as HPAGE_PMD_SHIFT is defined as BUILD_BUG in that case.

Fixes: abceb4297bf8 ("mshv: Fix huge page handling in memory region
traversal")
