mlx4_core: Set RAE and init mtt_sz field in FRMR MPT entries
Set the RAE (remote access enable) bit and correctly initialize the MTT size in MPT entries being set up for fast register memory regions. Otherwise the callers can't enable remote access and in fact can't fast register at all (since the HCA will think no MTT entries are allocated).
