comedi: jr3_pci: Fix synchronous deletion of timer

Browse source 
When `jr3_pci_detach()` is called during device removal, it calls
`timer_delete_sync()` to stop the timer, but the timer expiry function
always reschedules the timer, so the synchronization is ineffective.

Call `timer_shutdown_sync()` instead.  It does not matter that the timer
expiry function pointer is cleared, because the device is being removed.
