Stop enforcing (insn->src_reg == 0) and allow special verifier insns such as "BPF_LD_MAP_FD(BPF_REG_2, 0)", used to refer to a process-local map fd and introduced in 0246e64d9a5f ("bpf: handle pseudo BPF_LD_IMM64 insn"). This is consistent with other JITs such as riscv32 and also used by test_verifier (e.g. "runtime/jit: tail_call within bounds, prog once").
