ocfs2: Remove mount/unmount votes
The node maps that are set/unset by these votes are no longer relevant, thus we can remove the mount and umount votes. Since those are the last two remaining votes, we can also remove the entire vote infrastructure. The vote thread has been renamed to the downconvert thread, and the small amount of functionality related to managing it has been moved into fs/ocfs2/dlmglue.c. All references to votes have been removed or updated. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
