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.
