[Lldb-commits] [lldb] [lldb][PlatformDarwin][NFC] Use early-return style in LoadScriptingResourceInTarget (PR #186392)

[Michael Buch via lldb-commits]

https://github.com/Michael137 created https://github.com/llvm/llvm-project/pull/186392

Planning on adding more to this function/loop soon. Making it early-return style (as suggested by the LLVM style guide makes those changes easier to reason about).
