V4L/DVB (13409): firedtv: packet requeuing is likely to succeed
Packet DMA buffers are queued either initially all at once (then, a
queueing failure will cause firedtv to release the DMA context as a
whole) or subsequently one by one as they recycled after use (then a
failure is extremely unlikely). Therefore we can be a little less
cautious when counting at which packet buffer to set the interrupt flag.
