description:
audio(4): Fix an (unintended) minor behavior on AUDIO_FLUSH.
On NetBSD7, when AUDIO_FLUSH was issued, .offset of AUDIO_GETOOFFS was
reinitialized (to one block ahead from zero) or unchanged depend on
whether the user encoding is hardware native or not (probably).
I don't believe that it's intended or we need to maintain it.
Now, AUDIO_FLUSH always clears the offset to zero.
