Log Message:
avoid integer overflow when calculating inactive target.

on one of my systems, when UVM_PCTPARAM_APPLY() is used to calculate
s_inactarg, (s_active + s_inactive) * pct_scaled -- eg, (27484702 +
263661) * 84 == 2330862492, aka overflow in 32-bit signed, and then
code to enforce the inactive target to be at least the free target
would trigger and inactive target would be a small value.
