riscv, bpf: Enable inline bpf_kptr_xchg() for RV64
RV64 JIT supports 64-bit BPF_XCHG atomic instructions. At the same time,
the underlying implementation of xchg() and atomic64_xchg() in RV64 both
are raw_xchg() that supported 64-bit. Therefore inline bpf_kptr_xchg()
will have equivalent semantics. Let's inline it for better performance.
