drm/xe: Don't trigger rebind on initial dma-buf validation
On the first validate of an imported dma-buf (initial bind), the device
has no GPU mappings, so a rebind is unnecessary. Rebinding here is
harmful in multi-GPU setups and for VMs using preempt-fence mode, as it
would evict in-flight GPU work.
v2:
- Drop dma_buf_validated, check for XE_PL_SYSTEM (Thomas)
