When we stop an endpoint in release_urbs(), it ignores the inconsistent endpoint state and tries to release the resources. This shouldn't happen in theory, but it's still safer to abort the release and let the caller proper error handling. Also, stop_and_unlink_urbs() called from release_urbs() does two step works, and it's more straightforward to split this to two functions again, so that the call from the PCM trigger won't take the path with sleeping. This patch modifies the EP management code to adapt two points above.
