Xiaomi MiIO Remote: Lazy discover disabled

[syssi]

The Chuang Mi IR Remote Controller wants to be re-discovered every 5 minutes. As long as polling is disabled the device should be re-discovered in front of every command.

Improves sporadic timeouts/retries (if the device needs to be re-discovered):

I would much prefer if this would use kwargs instead of args (and maybe adding a short comment), if just to make it more readable for anyone stumbling upon why this is done.

Sorry, somehow forgot about this, looks good even if a bit verbose :-)
