Vic Yang a9541220dc Only waste 1 byte in queue buffer ...

For simplicity of the code, we don't allow (head == tail) when the queue
is full. But currently we are wasting the size of a single unit, while
we can actually just waste 1 byte. Let's fix this.

BUG=None
TEST=Pass the unit test.
BRANCH=None
