[PATCH] adapter: Fix accessing NULL adv_manager

[Szymon Janc <szymon.janc@codecoup.pl>]

adv_manager might be NULL also if BR/EDR only mdoe is set in main.conf
or if btd_adv_manager_new failed so checking for LE in supported
settings is not enough. This also makes btd_adv_manager_refresh
consistent with other adv_manager API regarding passing NULL manager
as function parameter.
