ASoC: Initialize val to avoid access garbage value

Browse source 
In DAPM, when booting up widgets connect variable
is sometimes initialized with value 1 even though
expected to be 0. This is due to val not initialized
locally in API dapm_set_mixer_path_status and can
result in using garbage value.
