MLK-19597: ISI: fix m2m hang issue after receiving 254 frames

In order to use ISI ping-pong buffer, driver add another list
for V4L2 m2m cap_q queue and add new list member to it from
cap_q default list without decreasing the related counter, so
it leads to overflow when run 254 times. So correct it.
