brcm80211: fmac: changed two scan related structures
struct brcmf_scan_results contained a 1 element array, but in reality the number of scan results can be 0 or more, as indicated by the count field in the same struct. Array has be redefined to be 0 elements length to indicate the array is purely for reference.
