[PATCH] ocfs2: add dlm_wait_for_node_death
* add dlm_wait_for_node_death function to be used after receiving a network
error. this will wait for the given timeout to allow the heartbeat
callbacks to update the domain map. without this, some paths may spin
and consume enough cpu that the heartbeat gets starved and never updates.
