[Mesa-dev] [PATCH] mesa: Fix error code for glTexParameteri of TEXTURE_MAX_LEVEL.

[Kenneth Graunke]

Calling glTexParameteri() with pname GL_TEXTURE_MAX_LEVEL and either a
target of GL_TEXTURE_RECTANGLE or a negative value previously generated
GL_INVALID_OPERATION.  However, GL_INVALID_VALUE seems more appropriate.

Fixes oglconform's api-error/negative.glTexParameter and es3conform's
sgis_texture_lod_basic_error.
