ocfs2/dlm: Use negotiated o2dlm protocol version
Patch fixes a bug in the o2dlm protocol negotiation in that it is using
the builtin version rather than the negotiated version during the domain
join. This causes join errors when a node having kernel >= 2.6.37 joins
a cluster with nodes having kernels < 2.6.37.
This only affects the o2cb cluster stack.
