Partial MFC of revision 1.16.
Change KASSERT() in feed_vchan16() into an explicit test and call to
panic() so that the buffer overflow just beyond this point is always
caught, even when the code is not compiled with INVARIANTS.
This will cause a deterministic panic if a particular combination of
sound hardware and client software triggers the buffer overflow in the
vchan code. This is better than letting the system panic in some
unrelated part of the kernel because of heap corruption.
