ubiattach: fail if kernel ignores max_beb_per1024
If the kernel doesn't know the max_beb_per1024 parameter in the attach
ioctl, but the call still succeeded ubi_attach and ubi_attach_mtd will
return 1 instead of 0.
In this case, the ubiattach command will detach the device and fail with
an error message.
