Sage Weil f61698d564 cls_rbd: remove old assign_bid method
This method is problematic because it both writes/mutates and returns data,
which means that an untimely client disconnect or peering event will result
in a success to the client with no payload.

It has not been used since v0.52 (18054ba46f)
which is pre-bobtail; so this change breaks compatibility with pre-bobtail
librbd clients (at least for image creation).

~~~~~
* 'ceph osd crush set <id> <weight> <loc..>' no longer adds the osd to the
specified location, as that's a job for 'ceph osd crush add'. It will
however continue to work just the same as long as the osd already exists
in the crush map.
* The OSD now enforces that class write methods cannot both mutate an
object and return data. The rbd.assign_bid method, the lone
offender, has been removed. This breaks compatibility with
pre-bobtail librbd clients by preventing them from creating new
images.
