media: amphion: Clear last_buffer_dequeued flag for DEC_CMD_START
[ Upstream commit d85f3207d75df6d7a08be6526b15ff398668206c ]
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.
