ocfs2: Hang the locking proto on the cluster conn and use it in asts.
With the ocfs2_cluster_connection hanging off of the ocfs2_dlm_lksb, we have access to it in the ast and bast wrapper functions. Attach the ocfs2_locking_protocol to the conn. Now, instead of refering to a static variable for ast/bast pointers, the wrappers can look at the connection. This means different connections can have different ast/bast pointers, and it reduces the need for the static pointer. Signed-off-by: Joel Becker <joel.becker@oracle.com>
