mesa: Fix error code for GetFramebufferAttachmentParameter in ES 3.0+.
The ES 3.0+ specifications contain the exact same text as the OpenGL
specification, which says that we should return GL_INVALID_OPERATION.
ES 2.0 contains different text saying we should return GL_INVALID_ENUM.
Previously, Mesa chose the error code based on API (GL vs. ES).
This patch makes ES 3.0+ follow the GL behavior. ES 2 remains as is.
Fixes dEQP-GLES3.functional.fbo.api.attachment_query_empty_fbo.
However, breaks the dEQP-GLES2 variant of the same test for drivers
which silently promote to ES 3.0. This can be worked around by
exporting MESA_GLES_VERSION_OVERRIDE=2.0, but is a bug in dEQP-GLES2.
