[PATCH md ] When resizing an array, we need to update resync_max_sectors as well as size.

Another md patch against 2.6.13-rc2-mm2, suitable for 2.6.13. Thanks, NeilBrown ### Comments for Changeset Without this, and attempt to 'grow' an array will claim to have synced the extra part without actually having done anything.
