[PATCH 3/8] media: flexcop-usb: fix control-message timeouts

[Johan Hovold]

USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.

Note that the driver was multiplying some of the timeout values with HZ
twice resulting in 3000-second timeouts with HZ=1000.

Also note that two of the timeout defines are currently unused.

Fixes: 2154be651b90 ("[media] redrat3: new rc-core IR transceiver device driver")
