draw: fix non-perspective interpolation in interp()

This fixes a regression from ab74fee5e1a3fc3323b7238278637b232c2d0d95.
When we use the clip coordinate to compute the screen-space interpolation
factor, we need to first apply the divide-by-W step to the clip
coordinate.

Fixes http://bugs.freedesktop.org/show_bug.cgi?id=60938

Note: This is a candidate for the 9.1 branch.
