mon/PGMap: avoid negative pg stats when calculating rates

We periodically see strange values come out of the estimated cluster
throughput and recovery rates.  Pretty sure this is cause by feeding
negative values into the rate arithmetic and then giving the si_t
helpers mangled (sign-extended + bit shifted) values.
