GFS2: Set gl_object during inode create
This patch fixes a cluster coherency problem that occurs when one node creates a file, does several writes, then a different node tries to write to the same file. When the inode's glock is demoted, the inode wasn't synced to the media properly because the gl_object wasn't set. Later, the flush daemon noticed the uncommitted data and tried to flush it, only to discover the glock was no longer locked properly in exclusive mode. That caused an assert withdraw.
