V4L/DVB (6548): pvrusb2: Fix oops on module removal
The pvrusb2 driver is tearing down its sysfs related pieces in the incorrect order. This leaves dangling pointers which causes the kernel device core to oops. The problem has been present virtually forever but became malignant with the changeover to the way of handling /sys/class. Fix is just to make sure we don't tear down the class structure until AFTER the driver instances are deregistered.
