KVM: arm/arm64: Fix check for hugepage size when allocating at Stage 2
Commit 45ee9d5e97a4 ("KVM: arm/arm64: Check pagesize when allocating a
hugepage at Stage 2") lost the check for PMD_SIZE during the backport
to 4.9.
Fix this by correcting the condition to detect hugepages during stage
2 allocation.
