net/netif_receive_skb_core: Use migrate_disable()
The preempt disable around do_xdp_generic() has been introduced in
commit
bbbe211c295ff ("net: rcu lock and preempt disable missing around generic xdp")
For BPF it is enough to use migrate_disable() and the code was updated
as it can be seen in commit
3c58482a382ba ("bpf: Provide bpf_prog_run_pin_on_cpu() helper")
This is a leftover which was not converted.
Use migrate_disable() before invoking do_xdp_generic().
