The recent fix to pmem_pagemap_cleanup() to solve a NULL pointer dereference with the queue_to_disk() helper neglected to remove the @q variable when queue_to_disk() was replaced.
Drop the conversion of @pgmap to its containing 'struct request_queue' since pgmap->owner supersedes the need to reference @q.
