radioDevice: Drop unused isControl param from WriteSamples API
The out "isControl" parameter is only used by internal callers of USRPDevice, and not used at all by any user of the generic API (radioInterface*.cpp). Hence, we can get rid of it and keep it as a flag for an internal API of USRPDevice. Change-Id: I843384e24b76cdd28a95f9ee4e95e6157098e4a3
