    nvme: move the Samsung X5 quirk entry to the core quirks
    
    [ Upstream commit e6487833182a8a0187f0292aca542fc163ccd03e ]
    
    This device shares the PCI ID with the Samsung 970 Evo Plus that
    does not need or want the quirks.  Move the the quirk entry to the
    core table based on the model number instead.
