media: imx-jpeg: Drop the first error frames

commit d52b9b7e2f10d22a49468128540533e8d76910cd upstream.

When an output buffer contains error frame header,
v4l2_jpeg_parse_header() will return error, then driver will mark this
buffer and a capture buffer done with error flag in device_run().

But if the error occurs in the first frames, before setup the capture
queue, there is no chance to schedule device_run(), and there may be no
capture to mark error.

So we need to drop this buffer with error flag, and make the decoding
can continue.
