freedreno/ir3: ignore clip-vertex varying

Browse source 
Since we emulate clip-planes, the clip-vertex is used within the VS
itself (thanks to nir_lower_clip).  So just ignore it as a VS output.
Fixes a boatload of piglit tests that were asserting on unknown
varying slot.

(Also unrelated spelling/typo fix.)
