ACPICA: On AML mutex force-release, set depth to zero (was 1).

 *

 * DESCRIPTION: Release all mutexes held by this thread

 *

 * NOTE: This function is called as the thread is exiting the interpreter.

 * Mutexes are not released when an individual control method is exited, but

 * only when the parent thread actually exits the interpreter. This allows one

 * method to acquire a mutex, and a different method to release it, as long as

 * this is performed underneath a single parent control method.

 *
