bpf/verifier: reject invalid LD_ABS | BPF_DW instruction
[ Upstream commit d82bccc69041a51f7b7b9b4a36db0772f4cdba21 ]
verifier must check for reserved size bits in instruction opcode and
reject BPF_LD | BPF_ABS | BPF_DW and BPF_LD | BPF_IND | BPF_DW instructions,
otherwise interpreter will WARN_RATELIMIT on them during execution.
Fixes: ddd872bc3098 ("bpf: verifier: add checks for BPF_ABS | BPF_IND instructions")
