Bluetooth: Fix kernel oops triggered by hci_adv_monitors_clear() 



This fixes the kernel oops by removing unnecessary background scan
update from hci_adv_monitors_clear() which shouldn't invoke any work
queue.

The following test was performed.
- Run "rmmod btusb" and verify that no kernel oops is triggered.
