Merge branch 'Avoid dummy bpf_offload_netdev in __bpf_prog_dev_bound_init'
Eduard Zingerman says:
====================
For a device bound BPF program with flag BPF_F_XDP_DEV_BOUND_ONLY,
in case if device does not support offload, __bpf_prog_dev_bound_init()
creates a dummy bpf_offload_netdev struct with .offdev field set to NULL.
This dummy struct might be reused for programs without this flag
bound to the same device. However, bpf_prog_offload_verifier_prep()
that uses bpf_offload_netdev assumes that .offdev field cannot be NULL.
This bug was reported by syzbot in [1].
