[PATCH] ctrl_iface: Send an event when an inactive station is removed

[Nicolas Cavallari]

Currently there is no events over the control interface when
a station is removed due to inactivity.  With this patch, an
"AP-INACTIVE-STA-DISCONNECTED"  event is sent when a station
is removed.

This doesn't break anything for existing applications which
expect that an "AP-STA-DISCONNECTED" event mean an explicit
disassociation from the client.
