avcodec/utils: apply the same alignment to YUV410 as we do to YUV420 for snow

The snow encoder uses block based motion estimation which can read out of array if
insufficient alignment is used

It may be better to only apply this for the encoder, as it would safe a few bytes of memory
for the decoder. Until then, this fixes the issue in a simple way.

It seems reply1 is initialized by ff_rtsp_send_cmd() in most cases but there
are code paths like "continue" which look like they could skip it but even if not
writing this so a complex loop after several layers of calls initialized a local
