[RISCV][NFC] Change interface of RVVIntrinsic::getSuffixStr

[kito-cheng]

Summary

This NFC patch is splited from D111617.

Using llvm::ArrayRef rather than llvm::SmallVector, ArrayRef is more generic
interface that could accept both llvm::ArrayRef and llvm::SmallVector.

Changes:

• Fix dumb typo...

Changes:

• clang-format has applied on unexpected part, remove that.
