The previous patch to allow the hwspinlock code to be disabled missed handling the free in the error path, do so using the better IS_ENABLED() pattern as suggested by Baolin. While we're at it also check that we have a hardware spinlock before freeing it - the core code reports an error when freeing an invalid lock.
