When the enic was disabled, link notification was correctly disabled
in the NIC but the software indicator that it was disabled was not
updated (vdev->notify_pa not set to 0). When the link came back up,
enic did not re-enable notification in the NIC.
This affected bonding when a enic slave device link bounced.
The fix is to unconditionally enable notification when the enic is
enabled.
