When vm-binding an already-created BO, the entirety of its virtual size is
then backed by system memory, so its RSS is always the same as its virtual
size.
Also, we consider a PRIME imported BO to be resident if its matching
dma_buf has an open attachment, which means its backing storage had already
been allocated.
