From: Ming Qian <ming.qian@oss.nxp.com>

The V4L2_DEC_CMD_START command may be used to handle the dynamic source
change, which will triggers an implicit decoder drain.
The last_buffer_dequeued flag is set in the implicit decoder drain,
so driver need to clear it to continue the following decoding flow.
