ionic: leave netdev mac alone after fw-upgrade
When running in a bond setup, or some other potential configurations, the netdev mac may have been changed from the default device mac. Since the userland doesn't know about the changes going on under the covers in a fw-upgrade it doesn't know the re-push the mac filter. The driver needs to leave the netdev mac filter alone when rebuilding after the fw-upgrade.
