[PATCH] Bluetooth: HCI: fix disabling of adv instance before updating params

[PATCH] Bluetooth: HCI: fix disabling of adv instance before updating params

[Christian Eggers]

struct adv_info::pending doesn't tell whether advertising is currently
enabled. This is already checked in hci_disable_ext_adv_instance_sync().

Fixes: cba6b758711c ("Bluetooth: hci_sync: Make use of hci_cmd_sync_queue set 2")
