bpf: Reject unwind_goto and unwind_exit in offloaded progs
A prog with unwind_goto or unwind_exit has to be JITed by a JIT that
supports them. The driver JITs an offloaded prog, and nobody looks at
jit_required there.
nfp rejects unwind_goto in nfp_verify_insn(). netdevsim takes everything.
Nothing runs such a prog, but it's not jited for bpf_insn_prepare_dump(),
which takes unwind_goto for BPF_CALL_ARGS and shows it as a call.
Fixes: a2d274771321 ("bpf: Add unwind_goto and unwind_exit insns")
