Subject: [PATCH] drivers: vxlan: vnifilter: free percpu vni stats on error path
In case rhashtable_lookup_insert_fast() fails inside vxlan_vni_add(), the
allocated percpu vni stats are not freed on the error path.
Free them on the rhashtable_lookup_insert_fast() error path in
vxlan_vni_add().
Found by Linux Verification Center (linuxtesting.org).
Fixes: 4095e0e1328a ("drivers: vxlan: vnifilter: per vni stats")
