Add u_int nstart, nend counters to consumer and providers so we will not
have to examine the stats structure to tell if we have outstanding I/O
requests.
Making them u_int improves the chance of atomic updates to them,
but risks roll-over. Since the only interesting property is if
they are equal or not, this is not an issue.
