Btrfs: fix wrong error returned by adding a device
Reproduce: $ mkfs.btrfs /dev/sdb7 $ mount /dev/sdb7 /mnt/btrfs -o ro $ btrfs dev add /dev/sdb8 /mnt/btrfs ERROR: error adding the device '/dev/sdb8' - Invalid argument Since we mount with readonly options, and /dev/sdb7 is not a seeding one, a readonly notification is preferred.
