vrrp: while delete vr can't delete multi virtual address.

Here is bug example:
vpp# create loopback interface
loop0
vpp# vrrp vr add loop0 vr_id 1 priority 100 192.168.1.1 192.168.1.2
vpp# vrrp vr del loop0 vr_id 1
vpp# vrrp vr add loop0 vr_id 1 priority 100 192.168.1.1 192.168.1.2
vrrp vr add: vrrp_vr_add_del returned -105
