Oh, I fixed this back in June and forgot to close the bug report.  Fixed by:

    mesa: Require mipmap completeness for glCopyImageSubData() at times.

    This patch makes glCopyImageSubData require mipmap completeness when the
    texture object's built-in sampler object has a mipmapping MinFilter.
    This is apparently the de facto behavior and mandated by Android's CTS.

    One exception is that we ignore format based completeness rules
    (specifically integer formats with linear filtering), as this is
    also the de facto behavior that until recently was mandated by the
    OpenGL 4.5 CTS.

    This was discussed with both the OpenGL and OpenGL ES working groups,
    and while everyone agrees this behavior is unfortunate and complicated,
    it is what it is at this point.  There was little appetite for relaxing
    restrictions given that all conformant Android drivers followed the
    mipmapping rule, and all conformant GL 4.5 implementations ignored the
    integer/linear rule.

    Fixes (on i965):
    dEQP-GLES31.functional.debug.negative_coverage.*.buffer.copy_image_sub_data
