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}".
