Subject: sink-input,source-output: Handle devices going away in unlink hooks

sink-input,source-output: Handle devices going away in unlink hooks

If a *_UNLINK_POST hook causes a sink-input/source-output's sink/source
to go away, the subsequent attempt to update the sink/source status will
cause an assert. We deal with this by checking the sink/source status
before trying to update it.
