ifupdown2 should allow speed setting even with duplicate iface stanzas

Browse Source 
Ticket: CM-6740
Reviewed By: roopa
Testing Done: tested multiple ifreloads with various test cases

In the case of duplicate iface stanzas where one of the stanzas sets
the link attributes, ifupdown2 was confused because the absence
of link attributes forced it to reset them to default values
(when they existed).

This patch tracks link changes and prevents resetting to defaults
only if there are no explicit settings configured.  Furthermore,
only the last interface processed (from the duplicates) will take
care of resetting to defaults.
