avcodec/v4l2_m2m: fix av_pix_fmt changing when multiple /dev/video* devices are probed

On the RPI, three different /dev/video devices exist (decoder, scaler, encoder).

When probing the devices in order, the originally requested pix fmt
would be mutated causing the wrong one to be chosen when a matching
device was finally found.
