Bluetooth: hci_sync: fix memory leak in hci_update_adv_data()

[ Upstream commit 1ed8b37cbaf14574c779064ef1372af62e8ba6aa ]

When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is
not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR
to pass the instance to callback so no memory needs to be allocated.
