ocfs2/net: fix uninitialized ret in o2net_send_message_vec()

mmotm/fs/ocfs2/cluster/tcp.c: In function ‘o2net_send_message_vec’:
mmotm/fs/ocfs2/cluster/tcp.c:980:6: warning: ‘ret’ may be used uninitialized in this function

It seems a real bug introduced by commit 9af0b38ff3 (ocfs2/net:
Use wait_event() in o2net_send_message_vec()).
