Correct a long-standing error in vm_object_page_remove(). Specifically,
pmap_remove_all() must not be called on fictitious pages. To date,
fictitious pages have been allocated from zeroed memory, effectively
hiding this problem because the fictitious pages appear to have an empty
pv list. Submitted by: Kostik Belousov
Rewrite the comments describing vm_object_page_remove() to better
describe what it does. Add an assertion. Reviewed by: Kostik Belousov
