r600: fix copy/paste bug for sampleMaskIn workaround 

The sampleMaskIn workaround (b936f4d1ca)
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.

Spotted by Eric Engestrom <eric.engestrom@intel.com>

Fixes: b936f4d1ca0d2ab1e828a "r600: partly fix sampleMaskIn value"
