media: imon_raw: prevent "nonsensical timing event of duration 0"

Sometimes the device sends IR data which is all space, no pulses
whatsoever. Add the end of this the driver will put the rc device into
idle mode when it already is in idle mode. The following will be logged:

rc rc0: nonsensical timing event of duration 0
rc rc0: two consecutive events of type space
