ASoC: cs42l43: Sync the hp ilimit works when removing the component

Synchronise the headphone ilimit work functions when removing the
component. These can only trigger whilst the headphone is enabled which
shouldn't be possible once the component is removed but the works rely
on the stashed component pointer so they should be shut down before the
code moves on from component remove.
