Subject: [RHEL7.5 PATCH 169/169] Monitor: Include containers in spare

 migration

Spare migration doesn't work for external metadata. mdadm skips

a container with spare device because it is inactive. It used to work

because GET_ARRAY_INFO ioctl returned valid structure for a container

and mdadm treated such response as active container. Current

implementation checks it in sysfs where container is shown as inactive.

Adapt sysfs implementation to work the same way as ioctl.
