[media] rtl2832_sdr: cleanup some set_bit() calls
This code works fine but static checkers complain. The test_bit()
function takes the bit number and not a mask. Then the other issue is
that we were using USB_STATE_URB_BUF which is BIT(0) instead of URB_BUF.
Also we were open coding that instead of using the test/clear/set_bit()
functions.
