ALSA: dummy: Properly shutdown the systimer at freeing

Browse Source 
Add timer_shutdown_sync() call at the free callback for systimer
backend, in order to make sure that we can release the resources.

This is only for hardening, and there shouldn't be any actual issue
that requires this change for now.
