rbd: drop original request earlier for existence check

Browse Source 
The reference to the original request dropped at the end of
rbd_img_obj_exists_callback() corresponds to the reference taken
in rbd_img_obj_exists_submit() to account for the stat request
referring to it.  Move the put of that reference up right after
clearing that pointer to make its purpose more obvious.
