Remove unused variables
Remove an impossible condition

uiIntraPeriod is unsigned, and thus can't ever be negative.

The subtraction on the line above can't ever make the value wrap
around either, since param_.uiIntraPeriod % uiGOPSize always is
smaller than or equal to param_.uiIntraPeriod. Thus, the check
never is necessary even if the value would be signed either.

This fixes warnings when building with clang.

Make sure the width/height is large enough in SetOptionEncParamExt

When using 4 downsampled layers, make sure the random width/height
is large enough that the downsampled layers don't have a zero size.

Since the value never will be too small now, there's no need to
use WELS_CLIP3 any longer.
