bpf: offload: don't use prog->aux->offload as boolean
We currently use aux->offload to indicate that program is bound
to a specific device. This forces us to keep the offload structure
around even after the device is gone. Add a bool member to
struct bpf_prog_aux to indicate if offload was requested.
