Subject: [PATCH] imsm: return correct uuid for volume in detail
Git-commit: b771faef931c798a4553db0a8c1366aff90079c6
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348

Fixes the side effect of the patch b6180160f ("imsm: save current_vol number")
- wrong UUID is printed in detail for each volume.
New parameter "subarray" is added to determine what info should be extracted
from metadata (subarray or container).
The parameter affects only IMSM metadata.
