ASoC: Intel: Skylake: Fix mcps freeup after module unbind failure

While cleaning resources on module pmd event, we check for return
of skl_unbind_modules(). On failure this causes leak as all modules
attached do not have resources freed.

So ignore return value of module unbind and continue freeing
resources. This makes dapm state and resources correct.
