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)
