[llvm] [WindowsSecureHotPatching] Remove redundant getGetElementPtr() (NFC) (PR #222019)

[Nikita Popov via llvm-commits]

https://github.com/nikic created https://github.com/llvm/llvm-project/pull/222019

This was creating a degenerate getelementptr without any indices,
which is equivalent to the base pointer and will fold away.
