swscale/unscaled: correctly copy semiplanar formats
This fixes multiple bugs with semiplanar formats like NV12. Not only do
these
false positive the grayscale format checks (because dst[2] in NULL), but
they
also copied an incorrect number of pixels.
Fixes conversions such as nv12 -> nv12, gray8 -> nv12, nv20le -> nv20be,
etc.
Fixes: #11239
