vxlan: Add missing VNI filter counter update in arp_reduce(). 

JIRA: https://issues.redhat.com/browse/RHEL-36610

commit b22ea4ef4c3438817fcb604255b55b0058ed8c64

    vxlan: Add missing VNI filter counter update in arp_reduce().

    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.
