From: "Dr. David Alan Gilbert" <linux@treblig.org>

osd_req_op_extent_osd_data_pagelist() was added in 2013 as part of
commit a4ce40a9a7c1 ("libceph: combine initializing and setting osd data")
but never used.

The last use of osd_req_op_cls_request_data_pagelist() was removed in
2017's
commit ecd4a68a26a2 ("rbd: switch rbd_obj_method_sync() to
ceph_osdc_call()")

Remove them.

If we don't use these methods, then it makes sense to remove it. We can take
them back in the case of real necessity in this functionality.
