aacraid: IOCTL fix
After getting the platform shutdown command "VM_CloseAll" response from the firmware, driver was getting configuration IOCTL request from the upper layers and it sends down to firmware. This causes firmware assert issue. This patch fixes the firmware assert issue. During the shutdown, if driver gets commands from the upper layer, driver sends error code to the upper layers.
