[TargetInstrInfo] replace redundant expression in getMemOpBaseRegImmOfs

Summary:
The expression for computing the return value of getMemOpBaseRegImmOfs has only
one possible value. The other value would result in a return earlier in the
function. This patch replaces the expression with its only possible value.
