BUG/MINOR: backend: free allocated bind_addr if reuse conn

Browse Source 
Fix a leak in connect_server which happens when a connection is reused
and a bind_addr was allocated because transparent mode is active. The
connection has already an allocated bind_addr so free the newly
allocated one.

No backport needed.
