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.
