drm/xe/vm: Skip ufence association for CPU address mirror VMA during MAP

Browse source

The MAP operation for a CPU address mirror VMA does not require ufence
association because such mappings are not GPU-synchronized and do not
participate in GPU job completion signaling.

Remove the unnecessary ufence addition for this case to avoid -EBUSY
failure in check_ufence of unbind ops.
