i965/fs: Always provide a default LOD of 0 for TXS and TXL
We already provide a default LOD for textureQueryLevels and texture() on
non-fragment stages. However, there are more cases where one is needed
such as textureSize(gsampler2DMS*) in SPIR-V. Instead of trying to list
out all of the cases one at a time, just provide the default for all TXS
and TXL operations. This fixes a shader validation error in the new
Sascha deferredmultisampling demo which uses textureSize(gsampler2DMS).
