ocfs2: o2net: fix connect expired

Set nn_persistent_error to -ENOTCONN will stop reconnect since the "stop" condition in o2net_start_connect() will be true.

stop = (nn->nn_sc ||

		(nn->nn_persistent_error &&
		(nn->nn_persistent_error != -ENOTCONN || timeout == 0)));

This will make connection never be established if the first connection request is lost.

Set nn_persistent_error to 0 when connect expired to fix this. With this changes, dlm will not be waken up when connect expired, this is OK since dlm depends on network, dlm can do nothing in this case if waken up. Let it wait there for network recover and connect built again to continue.
