Currently, the ath12k_get_num_hw() helper function takes the device handle as an argument. Here, the number of hardware is retrieved from the group handle. Demanding the device handle from the caller is unnecessary since in some cases the group handle is already available. Therefore, change this helper function argument from the device handle to the group handle. This also fixes the below Smatch static checker warning.
