venus: avoid feedback for external fence

Browse Source 
Sync fd fence export implies a payload reset operation, and application
can immediately do another submission with the same fence after export.
Concurrent use of the same feedback slot is incorrect. Keeping a list of
feedback slots for sync_fd external fence is a bit over designed given
those fences are usually not checked or waited by the app, but will hand
off the ownership via sync fd to an external client.
