ocfs2: Do not initialize lvb in ocfs2_orphan_scan_lock_res_init()

We don't access the LVB in our ocfs2_*_lock_res_init() functions.

Since the LVB can become invalid during some cluster recovery
operations, the dlmglue must be able to handle an uninitialized
LVB.

For the orphan scan lock, we initialized an uninitialzed LVB with our
scan sequence number plus one.  This starts a normal orphan scan
cycle.
