qcacmn: Add qdf_thread_run and qdf_thread_join APIs

For cases where you want to create and immediately start a thread, the
Linux kernel has the kthread_run() API. Create a QDF wrapper for
kthread_run() as well as companion APIs for waiting for a thread to exit
and one to check if the current thread should exit.
