adapter: Don't refresh adv_manager for non-LE devices

btd_adv_manager_refresh is called upon MGMT_SETTING_DISCOVERABLE setting change
but as only LE adapters have an adv_manager, this leads to segmentation fault
for non-LE devices:

This commit prevents the call to btd_adv_manager_refresh for non-LE devices.
