ceph: eliminate req->r_wait_for_completion from ceph_mds_request
...and instead just pass the wait function on the stack.
Make ceph_mdsc_wait_request non-static, and add an argument for wait for
completion. Then have ceph_lock_message call ceph_mdsc_submit_request,
and ceph_mdsc_wait_request and pass in the pointer to
ceph_lock_wait_for_completion.
While we're in there, rearrange some fields in ceph_mds_request, so we
save a total of 24 bytes per.
