Subject: [PATCH] Grow: don't allow array geometry change with ppl enabled
Git-commit: b208f817ec538e56df7280f0353e6bda532b9432
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

Don't allow array geometry change (size expand, disk adding) when PPL
consistency policy is enabled. Current PPL implementation doesn't work when
reshape is taking place.
