Stefan Wahren 1817c4b850 staging: vchiq_arm: Fix possible NPR of keep-alive thread ...

[ Upstream commit 3db89bc6d9 ]

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.
