[Intel-gfx] [PATCH] tests/prime_self_import: Track leaked objects accurately

[Daniel Vetter]

drm_open_any keeps a buffer handle around for the cleanup sync work,
so we can only grab the buffer count after the latst drm_open_any
call. Otherwise we'll detect a fake leak.

This broke in

    lib/drmtest: don't dup quiescent fd

since that additional open drm fd keeps a gem object for the default
context around. Hence why this also only blows up on gen6+ - earlier
platforms don't have hw context support.
