[llvm] [PAuthLR] Fix Unannoted Fallthrough (PR #113883)

[Jack Styles via llvm-commits]

https://github.com/Stylie777 created https://github.com/llvm/llvm-project/pull/113883

There was a missing break, which led to an unannotated fallthrough when merging #112171. This has caused sanitizer builds to fail.

This adds the missing break in the switch statement to ensure that the fallthrough does not occur.
