[Qemu-block] [PATCH for-2.7 v2 1/2] throttle: Don't allow burst limits to be lower than the normal limits |

Setting FOO_max to a value that is lower than FOO does not make
sense, and it produces odd results depending on the value of
FOO_max_length. Although the user should not set that configuration
in the first place it's better to reject it explicitly.
