kernel-device-generic: Fix ptr_array_add_sysfs_attribute_link_basename

Browse Source 
A pointer can not be used anymore after its ownership has been transfered
using the g_steal_pointer function (pointer is nullified).

In this function, g_steal_pointer() is used when inserting 'value' inside
the array but can also be subsequently used when dumping 'value' to
'out_value' via g_strdup().

Fix that with simple reordering.
