mkfs: warning about misaligned AGs and RAID stripes is not an error
I've noticed a fair number of fstests failures when we create a scratch
device on a RAID device and the test specifies an explicit AG count or
AG size:

+Make a 96 megabyte filesystem on SCRATCH_DEV and mount... Warning: AG size is a multiple of stripe width. This can cause performance
+problems by aligning all AGs on the same disk. To avoid this, run mkfs with
+an AG size that is one stripe unit smaller or larger, for example 8160.
+done
Emitting this warning on stderr is silly -- nothing has failed, and we
aren't going to abort the format either. Send the warning to stdout.
