Matthijs Kooijman d62b681847 [media] rc: Set rdev before irq setup 
This fixes a problem in fintek-cir and nuvoton-cir where the
irq handler would trigger during module load before the rdev member was
set, causing a NULL pointer crash.
It seems this crash is very reproducible (just bombard the receiver with
IR signals during module load), probably because when request_irq is
called, any pending intterupt is handled immediately, before
request_irq returns and rdev can be set.
This same crash was supposed to be fixed by commit
9ef449c6b3 ("[media] rc: Postpone ISR
registration"), but the crash was still observed on the nuvoton-cir
driver.
This commit was tested on nuvoton-cir only.
