Using bcm2835-codec wastes dmesg (similar to #817)

[jjsuwa-sys3175]

Describe the bug

A problem similar to #817 also occurs with bcm2835-codec.

Steps to reproduce the behaviour

For example, using FFmpeg with h264_v4l2m2m for a very short time:

pi@Raspi3B:/tmp$ sudo dmesg -C; ffmpeg -hide_banner -y -t 2 -f v4l2 -input_format mjpeg -video_size 1920:1080 -framerate 30 -i /dev/video0 -c:v h264_v4l2m2m -num_capture_buffers 32 -pix_fmt yuv420p -b:v 2500k /tmp/test.mp4; dmesg
Input #0, video4linux2,v4l2, from '/dev/video0':
  Duration: N/A, start: 786.464202, bitrate: N/A
  Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080, 30 fps, 30 tbr, 1000k tbn
Stream mapping:
  Stream #0:0 -> #0:0 (mjpeg (native) -> h264 (h264_v4l2m2m))
