Subject: [PATCH] policy.c: Avoid to take spare without defined domain by imsm
Git-commit: 3bf9495270d7cd00da942e183dc5f7c7eb68ff69
Patch-mainline: mdadm-4.0+
References: bsc#1076588

Only Imsm get_disk_controller_domain returns disk controller domain for
each disk. It causes that mdadm automatically creates disk controller
domain policy for imsm metadata, and imsm containers in the same disk
controller domain can take spare for recovery.

Ignore spares if only one imsm domain is matched.
