protocol/server: put the connection back if setvolume fails
In server_setvolume, put the connection back (thus removing it from a the list of connections that protocol/server is maintaining if the connection object is a newly created one) if some operations such as getting the bound_xl etc fails. Otherwise the process might segfault upon statedump, when it tries to access NULL bound_xl of a connection.
