    LinuxKPI: 802.11: fix counting the number of supbands
    
    While the main purpose was to assign an(y) early chandef with the
    loop, later additions made use of it to also count supbands as well
    as to initialise max_rates.
    Due to the main goal we can exit the loop early and not properly
    count and initialise supbands and max_rates.
    Move the terminating condition into the loop and make it a continue
    rather than ending the loop.
    
    Fixes:          d9945d7821b9b ("improve hw_scan")
