Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()
KSAN reports use-after-free in hci_add_adv_monitor().
While adding an adv monitor,
hci_add_adv_monitor() calls ->
msft_add_monitor_pattern() calls ->
msft_add_monitor_sync() calls ->
msft_le_monitor_advertisement_cb() calls in an error case ->
hci_free_adv_monitor() which frees the *moniter.
This is referenced by bt_dev_dbg() in hci_add_adv_monitor().
Fix the bt_dev_dbg() by using handle instead of monitor->handle.
