LU-17261 lov: unlink can handle bogus striping

Allow removing a file which has uninitialized OST objects in the
layout, possibly because LFSCK reconnected an orphan object back
into a mirrored file after the mirror had been deleted.

Don't wait and retry to access the bogus OST or MDT index in this
case, because the target will never appear, so waiting is futile.
