Eliminate SLES10/OCFS2 support code from upstream

This is long overdue. The OCFS2 support code in the Filesystem RA was/is only functional on SLES10, requiring OCFS2 user-space integration code from 2008 that never was merged in the upstream kernel.

They will of course continue to be supported for the lifetime of SLES10, but it's sufficient if they remain in that product.
