Make softmac report a scan event when scanning has finished, that way
userspace can wait for the event to happen instead of polling for the
results.

This patch depends on the previous patch 4. If you want, I can resend
the whole series with proper patch x/5 headers etc. I don't know if
these can still go in before .17, but it'd be very good if they could,
they're essentially bug fixes for things I either didn't know or just
plain bugs :)
