Subject: [PATCH] intel: aubinator: print field values if available

Turning this :

sampler state 0
    Sampler Disable: false
    Texture Border Color Mode: 0
    LOD PreClamp Enable: 1
    Base Mip Level: 0.000000
    Mip Mode Filter: 0
    Mag Mode Filter: 1
    Min Mode Filter: 1
    Texture LOD Bias: foo
    Anisotropic Algorithm: 0

into this :

sampler state 0
    Sampler Disable: false
    Texture Border Color Mode: 0 (DX10/OGL)
    LOD PreClamp Enable: 1 (OGL)
    Base Mip Level: 0.000000
    Mip Mode Filter: 0 (NONE)
    Mag Mode Filter: 1 (LINEAR)
    Min Mode Filter: 1 (LINEAR)
    Texture LOD Bias: foo
    Anisotropic Algorithm: 0 (LEGACY)
