[llvm] [NFC][NVPTX] Cleanup getPreferredVectorAction() (PR #114115)

[Justin Fargnoli via llvm-commits]

https://github.com/justinfargnoli created https://github.com/llvm/llvm-project/pull/114115

`v2*16` is a legal type in NVPTX. Thus, rely on the default implementation of getPreferredVectorAction().
