    hostapd: ACS: fix channel 100 frequency
    
    Channel 100 is a valid channel to choose for 80MHz operation. However,
    it's assigned to 5500 MHz, not 5550MHz. In fact, there is no channel
    assigned to this frequency.
    
    Fix this obbvious typo to allow ACS to select channel 100 for 80 MHz
    operation again.
