ocfs2_dlmfs: Enable the use of user cluster stacks.

Browse source

Unlike ocfs2, dlmfs has no permanent storage.  It can't store off a
cluster stack it is supposed to be using.  So it can't specify the stack
name in ocfs2_cluster_connect().

Instead, we create ocfs2_cluster_connect_agnostic(), which simply uses
the stack that is currently enabled.  This is find for dlmfs, which will
rely on the stack initialization.

We add the "stackglue" capability to dlmfs's capability list.  This lets
userspace know dlmfs can be used with all cluster stacks.
