In theory yes, in practice if we keep ignore_suspend set then we get
audio for a couple of more seconds after suspend until the buffers
are empty, as we have no code keeping them filled, which is not really
useful, since we don't support this in a meaningful way it is better
to just do a normal full suspend.
