    rpc: bump up conn->cleanup_gen in rpc_clnt_reconnect_cleanup

    Commit 086436a introduced generation number (cleanup_gen) to ensure that
    rpc layer doesn't end up cleaning up the connection object if
    application layer has already destroyed it. Bumping up cleanup_gen was
    done only in rpc_clnt_connection_cleanup (). However the same is needed
    in rpc_clnt_reconnect_cleanup () too as with out it if the object gets
destroyed
    through the reconnect event in the application layer, rpc layer will
    still end up in trying to delete the object resulting into double free
    and crash.

    Peer probing an invalid host/IP was the basic test to catch this issue.
