--------------------------------

[ Upstream commit 1c2786632e20c8f0fd4004fae3b3490276e5e5da ]

The last buffer from before the change must be marked,
with the V4L2_BUF_FLAG_LAST flag,
similarly to the Drain sequence above.

Meanwhile if V4L2_DEC_CMD_STOP is sent before
the source change triggered,
we need to restore the is_draing flag after
the draining in dynamic resolution change.
