From: Colin Ian King <colin.k...@canonical.com>
arp is being checked instead of arp_eth to see if the call to
__skb_header_pointer failed. Fix this by checking arp_eth is
null instead of arp.
CoverityScan CID#1396428 ("Logically dead code") on 2nd
arp comparison (which should be arp_eth instead).
Fixes: commit 55733350e5e8b70c5 ("flow disector: ARP support")
