  b2b_logic: fix issues when new entities are unused

New entities created with b2b_server_new() or b2b_client_new() functions would
leak if they were not eventually used by a b2b_init_request() call. This would
lead to pkg memory leaks and bogus errors from successive calls to
b2b_init_request().

Also, fix an entity memory leak when using the b2b_bridge_retry() function
for a tuple that is in a non-initial bridging state (eg. triggered by
b2b_bridge_request()).
