video: driver: add dpb buffer handling for b2b ipsc cases

Browse Source 
Currently MSM_VIDC_BUF_DPB buffer allocated and queued to firmware
as part of output port streamon. Sometimes firmware raises b2b ipsc
with only change in fw_min_count. So client will not follow port
reconfig sequence and calls directly HFI_CMD_RESUME on output port.
So firmware holds only prev set of DPB buffers, which is not sufficient
and it continues to wait for further DPB buffers and that is leading
to stall and testcase fails. So added change to requeue new set of
DPB buffers, incase of b2b ipsc(with only change in count).
