ocfs2: Remove delete inode vote
Ocfs2 currently does cluster-wide node messaging to check the open state of an inode during delete. This patch removes that mechanism in favor of an inode cluster lock which is taken at shared read when an inode is first read and dropped in clear_inode(). This allows a deleting node to test the liveness of an inode by attempting to take an exclusive lock.
