Commit 528222d853f92 ("media: rc: harmonize infrared durations to
microseconds") missed to switch some timeout calculations from
nanoseconds to microseconds. This resulted in spurious key_up+key_down
events at the last scancode if the rc device uses a long timeout
(eg 100ms on nuvoton-cir) as the device timeout wasn't properly
accounted for in the keyup timeout calculation.
Fix this by applying the proper conversion functions.
