[LoongArch] Fix atomic instructions operands sequence

[SixWeining]

Summary

According to https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html#atomic-memory-access-instructions,
the operands sequence of am* instructions should be "rd, rk, rj"
but not "rd, rj, rk". Sorry for this typo in initial patches.

Here we are again, you're bitten by the inconsistent manual syntax, and I didn't notice because everything in the initial patch seemed perfectly symmetrical ;-)

Yes. This is indeed a typical example. :(
