libertas: terminate scan when stopping interface
There are currently no provisions in place to ensure that the scanning task has been stopped when the interface is stopped or removed. This can result in a WARNING at net/wireless/core.c:643 and other badness when you remove the module while a scan is happening. Terminate the scanning task during interface stop.
