[PATCH 1/4] rbd: drop oid parameters from ceph_osdc_build_request()

[Alex Elder <elder@inktank.com>]

The last two parameters to ceph_osd_build_request() describe the
object id, but the values passed always come from the osd request
structure whose address is also provided.  Get rid of those last
two parameters.
