[RISCV] Fix build failure in getIntrinsicInstrCost

[artagnon]

bd66fd0 ([CostModel/RISCV] Fix costs of vector [l](lrint|lround)) introduced buildbot failures by using a temporary ArrayRef when a SmallVector should have been used. Fix this.

Failure: https://lab.llvm.org/buildbot/#/builders/186/builds/11133
