radio: iris: Fix the possibility of NULL pointer access



- Fix the issue with null pointer access.
- When SSR triggers, SMD channel closes and
  FM driver will unregister the device.
- While unregister device, free the memory allocation
  of the device pointer.
- Added a NULL check, before accessing device.
