Subject: [PATCH 082/359] Grow: only warn about incompatible metadata when no
 fallback available.
References: bsc#1081910

We might be trying to set_new_data_offset() for RAID10, when it is
a necessary requirement, or for RAID5 where it is optional.
In the latter case, a message about metadata versions is no helpful.
