The condition for determining s_axis_ready only looks at whether we are
currently full, not whether we will be full on the next cycle (which is
what matters). Make it take into account whether we are going to
increment s_ptr during the current cycle. Also increase the ratio to
ensure we trigger this case, as a ration of 2 doesn't make the slave
slow enough to catch this.
