x86/shadow: adjust mask shadow_audit_tables() passes to hash_foreach()

It so far having been ~1 made most of the code preceding the call
pointless, but I assume this wasn't meant to be that way. Also replace
the remaining hard coded ~1 with an expression documenting the
intention a little better.

Adjust again to use SHF_page_type_mask, at Jan's suggestion.
