[SVE] Remove invalid usage of VectorType::getNumElements in Function 

Summary:
Removes usage of VectorType::getNumElements identified by test located
at CodeGen/aarch64-sve-intrinsics/acle_sve_dot.c. This code explicitly
converts a potentially fixed length vector to scalable vector by
constructing the ElementCount = {getNumElements(), true}
