Since commit 90020a760584 ("btrfs-progs: mkfs: refactor how we handle
sectorsize override") we have extra warning message if the sectorsize of
mkfs doesn't match page size.
But this warning is show as stderr, which makes a lot of fstests cases
failure due to golden output mismatch.
Fix this by manually output the warning message as stdout.
This is just a temporary fix, a proper fix would needs kernel
/sys/fs/btrfs/features/supported_rw_sectorsize interface to do proper
prompt.
