Heinz Mauelshagen 4ebfd8e8eb lvconvert: don't return success on degraded -m raid1 conversion
In case "lvconvert -mN RaidLV" was used on a degraded
raid1 LV, success was returned instead of an error.

Provide message to inform about the need to repair first
before changing number of mirrors and exit with error.

Add new lvconvert-m-raid1-degraded.sh test.
