avfilter/vf_scale: test return code of scale_frame()
Instead of testing the returned frame against NULL, test the return code
itself, going more in line with the usual behavior of such functions.

[FFmpeg-cvslog] avfilter/vf_scale: fix frame lifetimes

avfilter/vf_scale: fix frame lifetimes
scale_frame() inconsistently handled the lifetime of `in`. Fixes a
possible double free and a possible memory leak.
The new code always has `scale_frame` take over ownership of the input
frame. I first tried writing this code in a way where the calling code
retains ownership, but this is nontrivial due to the presence of the
no-op short-circuit condition in which the input frame is directly
returned. (As an alternative, we could use av_frame_clone() instead, but
I wanted to avoid touching the original behavior in this commit)

x86/intreadwrite: use intrinsics instead of inline asm for AV_ZERO128
When called inside a loop, the inline asm version results in one pxor
unnecessarely emitted per iteration, as the contents of the __asm__() block are
opaque to the compiler's instruction scheduler.
This is not the case with intrinsics, where pxor will be emitted once with any
half decent compiler.
This also has the benefit of removing any SSE -> AVX penalty that may happen
when the compiler emits VEX encoded instructions.
