gallium: make max_anisotropy a unsigned bitfield member
saves us a dword in sampler state, hw can't do non-integer aniso degree anyway. To allow aniso 1x (which seems of dubious value but some hardware (radeons) have such a mode, and even d3d allows specifiying it) redefine anisotropic filtering as disabled only if max_anistropy is 0.

max_anisotropy
Maximum filtering to apply anisotropically to textures. Setting this to
