MLK-9856: ASoC: imx-hdmi: fix the failure in module test

The alsa driver use shedule_delayed_work when close pcm in remove module.
But after remove module the resource is released, so there will be kernel dump.
So here use ignore_pmdown_time to avoid to use shedule_delayed_work, then this
issue can be avoided.
