[llvm] [BOLT][AArch64] Fix relocation type for `LDRSW` (PR #221939)

[Shanzhi Chen via llvm-commits]

https://github.com/chenshanzhi created https://github.com/llvm/llvm-project/pull/221939

Fix the incorrect relocation type for `LDRSW`. It should be `ELF::R_AARCH64_LDST32_ABS_LO12_NC`, but it was mistakenly set to `ELF::R_AARCH64_LDST64_ABS_LO12_NC` in PR #196051.
