lib/thread: Change spdk_thread_exit() to nest wrapper function and function body

Browse Source 
Change spdk_thread_exit() to nest a wrapper function, spdk_thread_exit()
and a static function made of function body. Include the check if the
state is running into the wrapper function.

These will make the following patches easier.
