A potential error in fs widget

[geekpi]

In rc.lua.copland of awesome-copycats project , 'used' may be a nil value and attempt to compare with number

fshomeupd = lain.widgets.fs({
    partition = "/home",
    settings  = function()
        if used < 90 then
            diskbar:set_color(beautiful.fg_normal)
        else
            diskbar:set_color("#EB8F8F")
        end
        diskbar:set_value(used / 100)
    end
})

You should have provided an example, or told how to reproduce this. Anyway I introduced a fallback.

Update lain module, and awesome-copycats as well.

Now used is fs_now.used. Same change is applied to available, size_mb and size_gb.
