Andreas Rheinhardt bcf707639e avcodec/svq3: Don't copy watermarked frame data twice ...

The SVQ3 decoder modifies the input bitstream at two places.
One of them is only reached when the file is watermarked.
Therefore commit 2264c11081
made a copy of all the frame data in this case.

But there is a second possibility for modifying the frame and
therefore Libav commit 1098f5c049
made the decoder always copy the data. This of course makes
the additional copy for watermarked frames redundant, but it hasn't
been removed. This commit does so.
