avcodec/h264_refs: Rewrite code to make control flow clearer

While this change IMO makes the control flow clearer
for the human reader, it is especially important for
GCC: It erroneously believes that it is possible to
enter the SHORT2(UNUSED|LONG) cases without having
entered the preceding block that initializes pic,
frame_num, structure and j; it would emit -Wmaybe-uninitialized
warnings for these variables if they were not pseudo-
initialized with av_uninit(). This patch allows to remove
the latter.
