Bluetooth: Implement disable and removal of adv instance
If ext adv is enabled then use ext adv to disable as well. Also remove the adv set during LE disable. < HCI Command: LE Set Extended Advertising Enable (0x08|0x0039) plen 2 Extended advertising: Disabled (0x00) Number of sets: Disable all sets (0x00) > HCI Event: Command Complete (0x0e) plen 4 LE Set Extended Advertising Enable (0x08|0x0039) ncmd 2 Status: Success (0x00) Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
