Also shouldn't we report some warning in case of such invalid

I think having the option to do so is a good idea. There are two cases
I can think of that you run into a "malicious" storage server:
1) Someone hacked your storage server
2) Your control plane allows your compute to connect to a user
provided storage service
Thinking as an admin, if I only allow storage servers I provide, then
I want to see such warnings. If I let people point the VMM to dodgy
servers, then I probably don't want the log spam.
For this reason, we generally don't log things for failed I/O requests.
If we wanted to introduce it, we'd better find a way to do so
consistently everywhere and not just in a single place with a one-off
option.
