libceph: don't set pages or bio in ceph_osdc_alloc_request()
Only one of the two callers of ceph_osdc_alloc_request() provides page or bio data for its payload. And essentially all that function was doing with those arguments was assigning them to fields in the osd request structure. Simplify ceph_osdc_alloc_request() by having the caller take care of making those assignments Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
