It's not always clear what the best way is to handle unexpected
conditions: whether with ASSERT(), domain_crash(), BUG_ON(), or some
other method. All methods have a risk of introducing security

There's no need to invoke get_page_from_gfn(), and there's also no need
to update the passed in frames[]. Invoke get_page_and_type() directly.
Also make the function's frames[] parameter const, change its return
type to int, and drop the bogus casts from two of its invocations.
