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.
