kvm: drop wrong assertion creating problems with pflash 

pflash toggles mr->romd_mode. So this assert does not always hold.

1) a device was added with !mr->romd_mode, therefore effectively not
   creating a kvm slot as we want to trap every access (add = false).
2) mr->romd_mode was toggled on before remove it. There is now
   actually no slot to remove and the assert is wrong.

So let's just drop the assert.
