PDO (Parallel Directory Operations) is now a standard ldiskfs feature.
The old patch series files that lacked PDO support have been removed
from the tree, so now we can drop all of the places that conditionally
use PDO, and just assume that PDO is standard.

Also remove support for rhel5 series file in ldiskfs, since that
no longer exists in the tree.
