[igt-dev] [PATCH i-g-t] lib/igt_draw: Fix bo leak in gpu draw routines

[Maarten Lankhorst]

gem_handle_to_libdrm_bo creates a new handle through the use of flink,
which makes kms_frontbuffer_tracking through a single run not complete
when it starts leaking 50MB objects. Add the missing bo_unref to kill
the duplicated handle and fix the leaks!
