Btrfs: use _IOR for BTRFS_IOC_SUBVOL_GETFLAGS
We used the wrong ioctl macro for the getflags ioctl before. As we don't have the set/getflags ioctls in the user space ioctl.h at the moment, it's safe to fix it now. Reviewed-by: David Sterba <dsterba@suse.cz> Signed-off-by: Alexander Block <ablock84@googlemail.com>
