Or we can avoid clearing up and freeing the buffers here until the
point where the buffers are returned by the host. Until that happens,
we can avoid taking new requests but return to the earlier caller with
timeout failure. That would avoid corruption, by freeing buffers
sooner, and not hanging of the kernel.
