Jeff Layton 6a81749ebe ceph: increment/decrement dio counter on async requests 
Ceph can in some cases issue an async DIO request, in which case we can
end up calling ceph_end_io_direct before the I/O is actually complete.
That may allow buffered operations to proceed while DIO requests are
still in flight.

Fix this by incrementing the i_dio_count when issuing an async DIO
request, and decrement it when tearing down the aio_req.

Fixes: 321fe13c93 ("ceph: add buffered/direct exclusionary locking for reads and writes")
