[PATCH] don't bring the interface down if WoWLAN is enabled

[Matteo Croce]

My concern was not only suspend/resume, but even wakeup from S5 which
means shutdown.
In that case wpa_s is stopped by the shutdown process and it will
bring the interface down.

Probably I had to document this feature better, sorry.
