[PATCH] ASoC: dont call dapm_sync while reporting jack always

[Vinod Koul <vinod.koul@intel.com>]

While reporting the jack status snd_soc_jack_report() invokes snd_soc_dapm_sync()
always. This should be required when we have pins associated with jack and
reporting enables or disables these.
So add a check for this case
