[gnome-disk-utility] Change label dialog hint

[Ondrej Holy <oholy src gnome org>]

commit 42ca8a15a4a6f90b7b99c01ac7b0eb8d62f02cdf
Author: Kai Lüke <kailueke riseup net>
Date:   Sun Apr 9 17:48:54 2017 +0200

    Change label dialog hint
    
    If the label matches the existing label the dialog
    does not proceed.
    
    Now an icon indicates this reason with a tooltip.
