Fix usage of deprecated netty method

This is done by preventing all calls to ChannelConfig.setAutoRead(false) during
the call to FMLNetworkHandler.fmlClientHandshake (the two @Redirects in
MixinNetworkDispatcher) and manually issuing the call before handleLoginSuccess
returns (at which point the NetHandlerPlayClient has been set).

This commit should be reverted once the issue mentioned above has been fixed.
