netdev: always honor disconnect events if issued by AP

Browse Source 
The disconnect event handler was mistakenly bailing out if FT or
reassociation was going on. This was done because a disconnect
event is sent by the kernel when CMD_AUTH/CMD_ASSOC is used.

The problem is an AP could also disconnect IWD which should never
be ignored.

To fix this always parse the disconnect event and, if issued by
the AP, always notify watchers of the disconnect.
