ASoC: fsl-asoc-card: Fix jack_event() always return 0

Today, hp_jack_event and mic_jack_event always return 0. However,
snd_soc_dapm_disable_pin and snd_soc_dapm_enable_pin may return a
non-zero value, this will cause the user who calling hp_jack_event
and mic_jack_event don't know whether the operation was really
successfully.
