hpilo: reduce frequency of IO operations
Change hpilo open and close logic to spin for 10usec between checking device, rather than every usec. Because the loop is coded to take up to 10ms, it seemed prudent to increase the interval between polling the device, to reduce the load on the system and allow more other work to happen.
