Subject: net: systemport: Be drop monitor friendly

net: systemport: Be drop monitor friendly

Utilize dev_consume_skb_any(cb->skb) in bcm_sysport_free_cb() which is
used when a TX packet is completed, as well as when the RX ring is
cleaned on shutdown. None of these two cases are packet drops, so be
drop monitor friendly.
