Bluetooth: bnep: Fix deadlock in session deletion
Commit f4d7cd4a4c introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by bnep_del_connection()
which is waiting for the thread to exit -- deadlock.
Use atomic_t/wake_up_process instead to signal to the thread to exit.
