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. https://bugzilla.redhat.com/show_bug.cgi?id=1355665 Signed-off-by: Alberto Garcia <berto@igalia.com> Reported-by: Gu Nini <ngu@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-id: 663d5aca406060e31f80d8113f77b6feee63b919.1469693110.git.berto@igalia.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
