Xiubo Li 732f861dd4 ceph: fix possible NULL pointer dereference for req->r_session ...

commit 7acae6183cf37c48b8da48bbbdb78820fb3913f3 upstream.

The request will be inserted into the ci->i_unsafe_dirops before
assigning the req->r_session, so it's possible that we will hit
NULL pointer dereference bug here.
