Xiubo Li a002274db5 ceph: do not access the kiocb after aio requests 
[ Upstream commit d1d9655052606fd9078e896668ec90191372d513 ]

In aio case, if the completion comes very fast just before the
ceph_read_iter() returns to fs/aio.c, the kiocb will be freed in
the completion callback, then if ceph_read_iter() access again
we will potentially hit the use-after-free bug.

[ jlayton: initialize direct_lock early, and use it everywhere ]
