mm/shmem: use pagevec_lookup in shmem_unlock_mapping
The comment shows that the reason for using find_get_entries() is now
stale; find_get_pages() will not return 0 if it hits a consecutive run of
swap entries, and I don't believe it has since 2011. pagevec_lookup() is
a simpler function to use than find_get_pages(), so use it instead.
