media: rc: ite-cir: fix min_timeout calculation

Browse Source 
Commit 528222d853 ("media: rc: harmonize infrared durations to
microseconds") missed to switch the min_timeout calculation from ns
to us. This resulted in a minimum timeout of 1.2 seconds instead of 1.2ms,
leading to large delays and long key repeats.

Fix this by applying proper ns->us conversion.
