Subject: rbd: fix error paths in rbd_img_request_fill()
From: Ilya Dryomov <[email protected]>
commit 42dd037c08c7cd6e3e9af7824b0c1d063f838885 upstream.
Doing rbd_obj_request_put() in rbd_img_request_fill() error paths is
not only insufficient, but also triggers an rbd_assert() in
rbd_obj_request_destroy():
Assertion failure in rbd_obj_request_destroy() at line 1867:
rbd_assert(obj_request->img_request == NULL);
rbd_img_obj_request_add() adds obj_requests to the img_request, the
opposite is rbd_img_obj_request_del(). Use it.
