Ilya Leoshkevich df34ec9db6 bpf: Fix atomic probe zero-extension 
Zero-extending results of atomic probe operations fails with:

    verifier bug. zext_dst is set, but no reg is defined

The problem is that insn_def_regno() handles BPF_ATOMICs, but not
BPF_PROBE_ATOMICs. Fix by adding the missing condition.

Fixes: d503a04f8b ("bpf: Add support for certain atomics in bpf_arena to x86 JIT")
