If aic3x_read failed , val is used uninitialized. Fix it by initializing val to 0.

This patch fixes below compile warning: sound/soc/codecs/tlv320aic3x.c: In function 'aic3x_get_gpio': sound/soc/codecs/tlv320aic3x.c:1183: warning: 'val' may be used uninitialized in this function sound/soc/codecs/tlv320aic3x.c: In function 'aic3x_headset_detected': sound/soc/codecs/tlv320aic3x.c:1211: warning: 'val' may be used uninitialized in this function sound/soc/codecs/tlv320aic3x.c: In function 'aic3x_button_pressed': sound/soc/codecs/tlv320aic3x.c:1219: warning: 'val' may be used uninitialized in this function
