Title: Deny sort command with store parameter when instance is cluster mode

It fixes #1645.

Actually it's more natural to throw CROSSSLOT if store parameter's key should stored to other node.
But I respect previous thing, "deny sort parameters related to multi key", and it's very easy to implement.

Please review and comment! Thanks!
