[Mesa-dev] [PATCH] r600: fix copy/paste bug for sampleMaskIn workaround

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

The sampleMaskIn workaround (b936f4d1ca0d2ab1e828ff6a6e617f12469687fa)
tries to figure out if the shader is running at per-sample frequency, but
there's a typo bug so it will only recognize per-sample linar inputs,
not per-sample perspective ones.
