radeonsi: fix viewport clipping handling. (v2)
If oViewport is written, vertex reuse need to be turned off.
If oViewport is constant, vertex reuse is fine, and VPORT_PROVOKE_DISABLE
need to be set. (We don't know if oViewport is constant so we
skip this.)
Fixes: arb_viewport_array-render-viewport-2 and some CTS tests.
v2: drop writing to provoke disable, drop write in initial
state.
