Convert the normal packet completion path to dev_consume_skb_any() so
packet drop profiling via dropwatch or perf top -G -e skb_kfree_skb
is not cluttered with false hits.

Compile tested only.  There is a dev_kfree_skb_any() in the routine
ixgbe_ptp_tx_hwtstamp() in ixgbe_ptp.c that looks like a conversion
candidate but I wasn't familiar enough with the code to pull the
trigger.
