Staging: rtl8188eu: overflow in update_sta_support_rate()

Browse source

commit 9dbd79aeb9 upstream.

The ->SupportedRates[] array has NDIS_802_11_LENGTH_RATES_EX (16)
elements.  Since "ie_len" comes from then network and can go up to 255
then it means we should add a range check to prevent memory corruption.
