softpipe: Fix textureLod with nonzero GL_TEXTURE_LOD_BIAS value
The level-of-detail bias wasn't simply added in the explicit LOD case.
This case seems to be tested only in piglit's
fs-texturequerylod-nearest-biased test, which is currently skipped, as
softpipe does not support textureQueryLod at the moment.
