[media] s5p-fimc: fix ISR and buffer handling for fimc-capture

In some cases fimc H/W did not stop although there were no output
buffers available. So the capture deactivation interrupt routine
is modified and the state of ST_CAPT_RUN is cleared only
in the LAST-IRQ call.

After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame.
(reference by user manual) So, S/W pointer should be increased too.
