msaa: Generate proper error for operations prohibited on MSAA buffers.
From the GL 3.0 spec, section 4.3.3, in the documentation for CopyPixels(): "An INVALID_OPERATION error will be generated if the object bound to READ_FRAMEBUFFER_BINDING is framebuffer complete and the value of SAMPLE_BUFFERS is greater than zero." The same applies to CopyTexImage...() and CopyTexSubImage...() functions, since they are defined in terms of CopyPixels(). Previously we were generating an INVALID_FRAMEBUFFER_OPERATION error in these cases. Fixes piglit tests "EXT_framebuffer_multisample/negative-{copypixels,copyteximage}".
