msm: vidc: Avoid sending CONTINUE_DATA_TRANSFER packet for venus 3xx

When client enables smooth streaming, video driver is sending
CONTINUE_DATA_TRANSFER packet to the firmware which is not
required. Sending this property results in video failures.
This change will fix the issue by not sending the packet at all.
