This is also the reason why this command has been used as the trigger to set the HCI_MGMT flag. However, when not running the user-space daemon and using command line tools it is possible that read_controller_info is not the first controller specific command. This patch moves the HCI_MGMT initialization to a generic place where it will be set for whatever happens to be the first mgmt command targetting a specific controller.
