The query_device callbacks that neither accept driver-specific input nor return a driver-specific response open-code the empty udata handling as ib_is_udata_in_empty() on entry and ib_respond_empty_udata() on exit. ib_no_udata_io() already combines both steps, so replace the entry check with it and simply return 0 on success. Unlike the create and destroy flows, query_device owns no uobject or HW resource - the extended path fills a stack ib_device_attr that the core discards on error - so clearing the empty response buffer on entry rather than on exit is a mechanical change with no functional difference.
