ALSA: hda - Check all inputs for is_active_nid_for_any()
commit 9d2b48f7304aafaefbf0794a556ab4e307929d24 upstream.
The is_active_nid_for_any() function in the generic parser is supposed
to check all connections from/to the given widget, but the current
code checks only the first input connection (index = 0).
This patch corrects the code to check all inputs by passing -1 to
index argument.
