Bluetooth: hci_core: Fix missing instances using HCI_MAX_AD_LENGTH
There a few instances still using HCI_MAX_AD_LENGTH instead of using
max_adv_len which takes care of detecting what is the actual maximum
length depending on if the controller supports EA or not.
Fixes: 112b5090c219 ("Bluetooth: MGMT: Fix always using HCI_MAX_AD_LENGTH")
