qcacmn: Send all args with unit test command for bangradar

The unit test command being sent to FW for bangradar did not have
enough arguments to perform subchannel marking as expected.

Pack in the existing uint32_t argument the following information
	1). Segment ID (2 bits)
	2). Chirp Information (1 bit)
	3). Frequency Offset (8 bits [can be signed]).
that is being sent in the unit test command structure.
