mm: pgtable: fix pte_swp_exclusive
Make pte_swp_exclusive return bool instead of int. This will better
reflect how pte_swp_exclusive is actually used in the code.
This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not
returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper
32-bits of PTE (like on alpha).
