valentinogeron 3c136a7777 EXEC with only read commands should not be rejected when OOM (#7696)
If the server gets MULTI command followed by only read
commands, and right before it gets the EXEC it reaches OOM,
the client will get OOM response.

So, from now on, it will get OOM response only if there was
at least one command that was tagged with `use-memory` flag
