staging: vchiq_arm: Fix possible NPR of keep-alive thread
In case vchiq_platform_conn_state_changed() is never called or fails before
driver removal, ka_thread won't be a valid pointer to a task_struct. So
do the necessary checks before calling kthread_stop to avoid a crash.
Fixes: 863a756aaf49 ("staging: vc04_services: vchiq_core: Stop kthreads on vchiq module unload")
