[PATCH 2/4] lib/xe/xe_ioctl: Add xe_vm_get_faults helper function

[Jonathan Cavitt]

Add a helper function, xe_vm_get_faults, that calls the
drm_xe_vm_get_faults ioctl.  Since the ioctl behaves similarly to an
xe_query in that it needs to be called once to get the size of the
return data and again to save the data, the helper function takes the
ioctl structure as a parameter.
