Subject: rbd: make sure pages are freed by libceph
Patch-mainline: Never, it fixes SUSE-specific code that has never been
   merged upstream
References: bsc#1045596

Changes made for FATE#321625 modified the rbd_dev_getxattr so that the
pages aren't tracked in a struct rbd_obj_request anymore, but in struct
ceph_osd_request instead.  By setting the 'own_pages' flag to true when
calling osd_req_op_xattr_response_data_pages ensures that libceph will
take care of freeing pages.
