stagefright aacenc: Avoid overflows when calculating normFactor normFactor is calculated using the saturating L_add function, but if the value added (*psfbPeFactors) is negative, the sum can end up negative. *psfbPeFactors can end up negative if redThrExp is less than *psfbNActiveLines. In cases where *psfbPeFactors ended up negative, normFactor became INT_MIN, causing division by zero later. Change-Id: I00c852e457b22f7eef4d6ed1887629828057206b
