[gparted] Make resize_move_partition() skip whole disk device partitions (#775932)

[Curtis Gedak <gedakc src gnome org>]

commit 7caebd2515509022ea8ec4fe505948ab1b758015

    Make resize_move_partition() skip whole disk device partitions (#775932)
    
    Make the logic at the resize_move_partition() call sites a little
    simpler by not having to avoid calling it for whole disk device
    partitions.  Make it a successful non-operation in that case.
    
    Bug 775932 - Refactor mostly applying of operations
