Subject: [PATCH 2/4] hostpad: nl80211: remove links while removing or
 de-initializing the interface

Currently, when interface is removed or is de-initialized, the links added
are not removed. While removing the interface/or via ifconfig down, kernel
removed the stale links. This is wrong since hostapd should remove and do
the clean ups properly while going down.

Hence add changes to remove links when interface is removed or
de-initialized.
