eq_iir: reduce logging verbosity during freeing

When pipelines are destroyed, component drivers' .reset() and .free()
are called. If those drivers were loaded dynamically their memory is
then unmapped. But logging takes place in a low priority task, so it
is important that no logging is done from those methods.
