IB/rdmavt: add modify queue pair driver helpers
Low level drivers need to be able to check incoming attributes as well as be able to adjust their private data on queue pair modification. Add 2 driver callbacks, check_modify_qp and modify_qp, to facilitate this. Signed-off-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
