IB/rdmavt: Add support for rvt_query_device function
With this commit, the drivers using rdmavt need not define query_device function. But they should fill in the IB device attributes structure rvt_dev_info.dparms.props Reviewed-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Harish Chegondi <harish.chegondi@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
