Subject: [PATCH iproute2-next 04/20] bridge: vni: Report duplicate vni argument using duparg()

When there is a duplicate 'vni' option, report the error using duparg()
instead of the generic invarg().

Before:
$ bridge vni add vni 100 vni 101 dev vxlan2
Error: argument "101" is wrong: duplicate vni

After:
$ ./bridge/bridge vni add vni 100 vni 101 dev vxlan2
Error: duplicate "vni": "101" is the second value.

Fixes: 45cd32f9f7d5 ("bridge: vxlan device vnifilter support")
