RISC-V: Remove unused arguments from ATOMIC_OP

Our atomics are generated from a complicated series of preprocessor
macros, each of which is slightly different from the last.  When writing
the macros I'd accidentally left some unused arguments floating around.
This patch removes the unused macro arguments.
