The destructor of AMDTP domain has WARN_ON() for the list of associated AMDTP stream. Although this reminds a case that developers forget to program consumer drivers to stop AMDTP domain, it hits when AMDTP domain is not initialized yet. This occurs when initialization of sound card fails as well and it's superfluous.
This commit removes the WARN_ON. Although the API to AMDTP domain does nothing, it's left for future usage.
