[ Upstream commit d9aef04fcfa81ee4fb2804a21a3712b7bbd936af ]
The type of "mwifiex_adapter->nd_info" is "struct cfg80211_wowlan_nd_info", not "struct cfg80211_wowlan_nd_match".
Use struct_size() to ease the computation of the needed size.
The current code over-allocates some memory, so is safe. But it wastes 32 bytes.
