x86: fix preemptable page type handling
- retain a page reference when PGT_partial is set on a page (and drop
it when clearing that flag)
- don't drop a page reference never acquired when freeing the page
type
of a page where the allocation of the type got preempted (and never
completed)
- don't acquire a page reference when allocating the page type of a
page where freeing the type got preempted (and never completed, and
hence didn't drop the respective reference)
