[media] it913x add retry to USB bulk endpoints and IO

Browse source

This a bus repeater for it913x devices. Commands usually fail because of other
activity on the USB bus.

Bulk failures that report -ETIMEDOUT or -EBUSY are repeated.

Enpoints that return actlen not equal len request -EAGAIN.

The retry is set at 10.
