vxlan: Add missing VNI filter counter update in arp_reduce().
[ Upstream commit b22ea4ef4c3438817fcb604255b55b0058ed8c64 ]
VXLAN stores per-VNI statistics using vxlan_vnifilter_count().
These statistics were not updated when arp_reduce() failed its
pskb_may_pull() call.
Use vxlan_vnifilter_count() to update the VNI counter when that
happens.
