SVN rev 196547 on 2009-08-25 16:59:55Z by thompsa
It is possible for all the kthreads to exit (hci modules unloaded) which in
turn ends our usb process. This means the proc pointer becomes invalid and will
panic if a new kthread is added. Count the number of threads and clear the proc
pointer on the last one.
