af_packet: Check return of dev_set_promiscuity/allmulti

dev_set_promiscuity/allmulti might overflow.  Commit: "netdevice: Fix
promiscuity and allmulti overflow" in net-next makes
dev_set_promiscuity/allmulti return error number if overflow happened.

In af_packet, we check all positive increment for promiscuity and
allmulti to get error return.
