[PATCH V2] mm/powerpc: Fix _PAGE_PTE breaking swapoff

Core kernel expect swp_entry_t to be consisting of only swap type and swap offset. We should not leak pte bits to swp_entry_t. This breaks swapoff which use the swap type and offset to build a swp_entry_t and later compare that to the swp_entry_t obtained from linux page table pte. Leaking pte
