proxy: Do not decrement proxy port reference count when reverting.
proxy: Do not decrement proxy port reference count when reverting.

Proxy port reference count is incremented only when an ACK has been received from
all proxies in a specific policy update. If any of the proxies fail to ACK in time,
the revert function is called. Proxy port reference counts must not be decremented
at this time, as they have not been incremented yet.
