drm/amdkfd: check for null dev to avoid a null pointer dereference
The call to kfd_device_by_id can potentially return null, so check that
dev is null and return with -EINVAL to avoid a null pointer dereference.
Detected by CoverityScan CID#1454629 ("Dereference null return value")
Fixes: 5d71dbc3a588 ("drm/amdkfd: Implement image tiling mode support v2")
