raid: limit the no superblock examine case 



Ignore raid bdevs that are not in CONFIGURING state or were assembled
from superblock.

For raid bdevs without superblock, examine is used only when some base
bdevs were not present at the time of raid bdev creation - the state is
CONFIGURING. When all bdevs are discovered, the raid bdev is activated
(ONLINE state) and any further examine calls on any bdev should have no
effect on this raid bdev.
