[media] iguanair: fix receiver overflow 

The Pioneer CU-700 remote causes receiver overflows if you hold down any
button. The remote does not send NEC IR repeats, it repeats the entire
NEC code after 20ms.

The iguanair hardware advertises an interval of 10 which just not enough;
with 100 URBs per second and at most 7 edges per URB, we handle at most
700 edges per second. The remote generates about 900.
