riff-media: Don't recurse in for nested WAVEFORMATEX

There was already a check for that, but it failed because
subformat_guid[0] is a guint32 and that is then casted implicitely to a
guint16 when recursing... just that we checked the uncasted value.

This caused an infinite recursion and thus stack overflow.
