ocfs2: Pass the locking protocol into ocfs2_cluster_connect().
Inside the stackglue, the locking protocol structure is hanging off of the ocfs2_cluster_connection. This takes it one further; the locking protocol is passed into ocfs2_cluster_connect(). Now different cluster connections can have different locking protocols with distinct asts. Note that all locking protocols have to keep their maximum protocol version in lock-step. With the protocol structure set in ocfs2_cluster_connect(), there is no need for the stackglue to have a static pointer to a specific protocol structure. We can change initialization to only pass in the maximum protocol version. Signed-off-by: Joel Becker <joel.becker@oracle.com>
