Fix a typo in lirc_ioctl, apparently min_timeout should be used

case LIRC_GET_MIN_TIMEOUT:

+ if (!dev->min_timeout)
So maybe this isn't the clearest piece of code, but all rc drivers set
either both of min_timeout & max_timeout, or neither. Having a max_timeout
without a min_timeout does not make any sense.
Changing this to min_timeout gives the impression min_timeout can be set
without max_timeout, which is not the case. This should at least commented.
Thanks

I agree, the necessary comments should be added here.
Thanks
