mac80211: fix a few work bugs
Kalle and Lennert reported problems with the new work
code, and at least Kalle's problem I was able to trace
to a missing jiffies initialisation.
I also ran into a problem where occasionally I couldn't
connect, which seems fixed with kicking the work items
after scanning.
Finally, also add some sanity checking code to verify
that we're not adding work items while an interface is
down -- that case could lead to something similar to
what Lennert was seeing.
There still seems to be a race condition that we're
trying to figure out separately.
