bpf, arm64: Enable the inline of bpf_kptr_xchg()
ARM64 bpf jit satisfies the following two conditions:
1) support BPF_XCHG() on pointer-sized word.
2) the implementation of xchg is the same as atomic_xchg() on
pointer-sized words. Both of these two functions use arch_xchg() to
implement the exchange.
So enable the inline of bpf_kptr_xchg() for arm64 bpf jit.
