  [LoopVectorize][SVE] Remove assert for scalable vector in InnerLoopVectorizer::fixReduction

The function fixReduction used to assert/crash for scalable vector when
a vector reduce could be done with a smaller vector.
This patch removes this assertion as it is safe to use scalable vector for
vector reduce and truncate.
