ENIC driver update to allow bonded interface admin down/up to pass traffic

enable traffic on bonded interface to resume properly on admin down and
then up of the bonded interface.

+Subject: [PATCH 1/2] net/enic: fix setting MAC address when a port is
+ restarted
+
+enic_disable() removed the MAC address when a port was shut down but
+enic_enable() didn't add the MAC address back when the port was
+started again. Move where we set the MAC address for the adapter from
+enic_setup_finish() to a enic_enable() so that port restarting works
+properly.
