If I understand correctly, this code is always executed after importing a 
buffer with an handle, a Gem name or a prime fd.

Given the imported buffer can be shared with another card (in the prime fd 
case), I imagine there are some cases where the buffer must stay in GTT.

What would happen in this case with your patch?
