30 * This function handles the command response error case.
32 * For scan response error, the function cancels all the pending
33 * scan commands and generates an event to inform the applications
34 * of the scan completion.
36 * For Power Save command failure, we do not retry enter PS
37 * command in case of Ad-hoc mode.
39 * For all other response errors, the current command buffer is freed
40 * and returned to the free command queue.
