ASoC: dapm: Fix pointer dereference in is_connected_output_ep()

*path is not yet initialized when we check if the widget is connected.

The compiler also warns about this:
sound/soc/soc-dapm.c: In function 'is_connected_output_ep':
sound/soc/soc-dapm.c:824:18: warning: 'path' may be used uninitialized in this function
