[PATCH 08/12] KVM: selftests: Use 'leaf' instead of hugepage to describe EPT entries

From: Yosry Ahmed <yosryahmed@google.com>

The assertions use 'hugepage' to describe a terminal EPT entry, but
'leaf' is more accruate as a PG_LEVEL_4K EPT entry is a leaf but not a
hugepage. The distincion will be useful in coming changes that will pass
the value around and 'leaf' is clearer than hugepage or page_size.

Leave the EPT bit named page_size to keep it conforming to the manual.
