[bpf-next,0/2] bpf: fix couple of netdevsim issues

Message

The first one is found by the syzkaller and needs to make a proper
distinction between offloaded and dev-bound cases.

The second one restores behavior where the offloaded/dev-bound programs
with a dead netdev were not correctly skipped during BPF_PROG_GET_NEXT_ID.

Stanislav Fomichev (2):
  netdevsim: don't accept device bound programs
  bpf: bring back removal of dev-bound id from idr
