staging/wlan-ng, prism2usb: replace reaper_bh tasklet with work
Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so.
The reaper_bh tasklet will now run in process context and have further
concurrency (tasklets being serialized among themselves), but this
is done holding the ctlxq.lock, so it should be fine.
