mm: swapoff: shmem_find_swap_entries() filter out other types
Swapfile "type" was passed all the way down to shmem_unuse_inode(), but then forgotten from shmem_find_swap_entries(): with the result that removing one swapfile would try to free up all the swap from shmem - no problem when only one swapfile anyway, but counter-productive when more, causing swapoff to be unnecessarily OOM-killed when it should succeed.
