media: flexcop-usb: fix control-message timeouts

BugLink: https://bugs.launchpad.net/bugs/1959376
commit cd1798a387825cc4a51282f5a611ad05bb1ad75f upstream.

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.
