While the MIPS64 JIT rejects programs with JMP32 insns, it still performs
initial static analysis. Add support in reg_val_propagate_range() for
BPF_JMP32, fixing kernel log WARNINGs ("Unhandled BPF_JMP case") seen
during JIT testing. Handle code BPF_JMP32 the same as BPF_JMP.
Fixes: 092ed0968bb6 ("bpf: verifier support JMP32")
