Remove promisc counter from parent interface in carp_clone_destroy(),

Browse source 
so that parent interface is not left in promiscous mode after carp
interface is destroyed.

This is not perfect, since promisc counter is added when carp
interface is assigned an IP address. However, when address is removed
parent interface is still in promiscuous mode. Only removal of
carp interface removes promisc from parent. Same way in OpenBSD.
