ASoC: Intel: Skylake: Simplify m_state for loadable modules

States SKL_MODULE_LOADED and SKL_MODULE_UNLOADED are redundant with
'loadable' flag in struct skl_module. Additionally
skl_tplg_mixer_dapm_post_pmd_event() sets m_state always to
SKL_MODULE_UNINIT so next unload function isn't called for such modules.
