Liam Girdwood 436dae6ae2 ASoC: dapm: Fix potential DAI widget pointer deref when linking DAIs
[ Upstream commit e01b4f624278d5efe5fb5da585ca371947b16680 ]

Sometime a component or topology may configure a DAI widget with no
private data leading to a dev_dbg() dereferencne of this data.

Fix this to check for non NULL private data and let users know if widget
is missing DAI.
