asoc: wcd-mbhc: report headset when it's not reported

During bootup and headset inserted, headset may first
detect as GND_MIC swap type and not report. During three
seconds polling, it's corrected as headset or headphone.
When wrk_complete is false, it will not report to userspace.
When current_plug is MBHC_PLUG_TYPE_NONE, report headset or
headphone to userspace.
