Subject: [PATCH] md/raid5: If there is a spare and a want_replacement device,
 start replacement.

When attempting to add a spare to a RAID[456] array, also consider
adding it as a replacement for a want_replacement device.

This requires that common md code attempt hot_add even when the array
is not formally degraded.
