fuse: add req flag for private list
When an unlocked request is aborted, it is moved from fpq->io to a private list. Then, after unlocking fpq->lock, the private list is processed and the requests are finished off. To protect the private list, we need to mark the request with a flag, so if in the meantime the request is unlocked the list is not corrupted.
