btrfs: move btrfs_raid_mindev_errorvalues to btrfs_raid_attr table
Add a new member struct btrfs_raid_attr::mindev_error so that btrfs_raid_array can maintain the error code to return if the minimum number of devices condition is not met while trying to delete a device in the given raid. And so we can drop btrfs_raid_mindev_error. Signed-off-by: Anand Jain <anand.jain@oracle.com> Reviewed-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
