 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
