mod_c2s: Disconnect accounts when they are disabled
We decided that at the first stage, accounts that are disabled should
simply be prevented from authenticating, thus they should also be
prevented from having connected sessions. Since this is aimed to be a
moderation action for cases of abuse, they shouldn't be allowed to
continue being connected.
