Martin Storsjö fc94a1acc2 Revert "libavutil: Use an intermediate variable in AV_COPY*U" 
This reverts commit 014773b66b.

Since 230b1c070, the bytewise AV_W*() macros only expand their
argument once, i.e. doing exactly the same change as was done
in the AV_COPY*U macros, so this change is no longer necessary.
