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.

+Fixes commit bef5eee4f7b2 ("Convert channel to frequency based selection for AP mode ACS")
