Hi,

I was initially only going to fix the thing in the last patch of this
set but after starting to look at the code I found several other issues
and hence the rest of the patches.

The first three patches fix work queue handling. We should, whenever
possible, avoid the system-global workqueue (the schedule_*work
functions) and use hdev-specific ones instead. However, we can't use
hci_request() with the usual workqueue since that would block e.g.
hci_send_cmd from completing so a second work queue is needed.

The last patch fixes a race with setting the scan mode that I was
seeing every once in a while through a connectable or discoverable test
case of mgmt-tester failing. There are several other HCI commands with
the same potential issue (like the class of device and the local name)
but I haven't gotten around to fixing those yet.

Johan
