media/gpu: Fix scoped_refptr parameter passing.

According to
https://chromium.googlesource.com/chromium/src/+/master/styleguide/c++/c++.md#object-ownership-and-calling-conventions
scoped_refptr should be passed by value, not by reference.

This CL focus on image_processor. More than 200+ lines need to be
fixed in media/gpu:
~/chrome/src/media/gpu$ grep -r "const scoped_refptr<.*>&" | wc
    226    1068   21515
