[PATCH v1 4/6] nl80211: Remove obsolete ifindex

[oleksandr.savchenko at celeno.com]

From: Alexander Savchenko <oleksandr.savchenko at celeno.com>

When the ifindex of the interface is changed, the obsolete ifindex is
not removed from the local ifidx list and have_idx()
can return false positive.
ifindex can be changed after calling of device_reprobe() in some wifi drivers.
