ceph: fix capsnap dirty pages accounting
writepages_finish() calls ceph_put_wrbuffer_cap_refs() once for all pages, parameter snapc is set to req->r_snapc. So writepages() shouldn't write dirty pages associated with different snapc in one OSD request. Signed-off-by: "Yan, Zheng" <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
