When asking hostapd to switch channel in the multi-BSS configuration,
only the first (associated to the first BSS) request is executed
correctly by some driver, other BSS's request are failing.
This is because multi-BSS configuration is using same Radio and one
request seems to be suffisant to driver to switch on.
Solution in here is to return SUCCESS if there was at least one BSS
switched OK.
