Subject: [PATCH] mesa: fix GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME query

Return 0 instead of generating an error.

See http://bugs.freedesktop.org/show_bug.cgi?id=30993

Note that piglit fbo-getframebufferattachmentparameter-01 still does
not pass.  But Mesa behaves the same as the NVIDIA driver in this case.
Perhaps the test is incorrect.

NOTE: This is a candidate for the 7.9 branch.
