Move atomic_inc(&ocfs2_control_opened) and the handshake state update
inside ocfs2_control_lock to close a race window where
ocfs2_control_release() can observe ocfs2_control_opened dropping to zero
(resetting ocfs2_control_this_node and running_proto) while
ocfs2_control_install_private() is about to bump the counter and mark the
connection valid.
