Stanislav Fomichev 41a0b3b8cf netdevsim: Don't accept device bound programs

[ Upstream commit c0c6bde586c7dce82719b4ff32a2db6af9ee3d65 ]

Commit 2b3486bc2d23 ("bpf: Introduce device-bound XDP programs") introduced
device-bound programs by largely reusing existing offloading infrastructure.
This changed the semantics of 'prog->aux->offload' a bit. Now, it's non-NULL
for both offloaded and device-bound programs.

Instead of looking at 'prog->aux->offload' let's call bpf_prog_is_offloaded
which should be true iff the program is offloaded and not merely device-bound.

Fixes: 2b3486bc2d23 ("bpf: Introduce device-bound XDP programs")
