If we get the final value of zero as a count of free
entries available, we will underflow our own fifo_count
and then it will take a long time before we check things again.
Admittedly we are in trouble already if we get into this situation,
but prevent the underflow by returning early.

If we get the final value of zero as a count of free
entries available, we will underflow our own fifo_count
and then it will take a long time before we check things again.
Admittedly we are in trouble already if we get into this situation,
but prevent the underflow by checking against zero before
