If cxl_device_lock() is used on a non-CXL device the expectation is that
the lock class will fall back to CXL_ANON_LOCK. Instead it crashes when
trying to determine if the device is a 'decoder'. Specifically when the
device has a NULL type pointer. Just check for NULL before
de-referencing ->release.
