    The correct option for label name in fat and vfat is '-n'

    The code in mkfs correctly extends the command line with a '-n' for
    vfat but does not currently do it for fat. This means that mkfs for
    fat ends up with a '-L' which is what you'd do for everything like
    ext[234].

    The change just treats fat like vfat in the one place where this check
    is required.
