[PATCH] md: split off some md attributes in sysfs to a separate group

Some, but not all, md array support data redundancy and hence support checking
and restoring that redundancy (resync, rebuild).

Some attributes apply specifically to functions involving this redundancy, and
so should only appear for md arrays for which they are meaningful.  i.e.  they
should not appear for raid0, linear, multpath, faulty.

This patch separates these into a distinct group and creates the group only if
the personality supports sync_request.
