qcacld-3.0: Fix improper QCN IE length filled

While filling the QCN IE the IE length filled is 11 while actual
length is 8 and thus this lead to improper IE length in scan
additional ie while copying the default_scan_ies.

So fix the QCN IE length and add check for improper IE length check
while copying IE in scan additional ie.
