  1. mon/PGMonitor: MAX AVAIL is 0 if some OSDs' weight is 0 

    In get_rule_avail(), even p->second is 0, it's possible to be used
as divisor and quotient is infinity, then is converted to an integer
which is negative value.
So we should check p->second value before calculation.

It fixes BUG ceph#13840.
