Undo the flex array in struct ieee80211_info_element. It is used as the flex
array type in other structs (creating a flex array of flex arrays) making
sparse unhappy. This change maintains the intent of the code and satisfies
sparse.

We have been trying to convert the kernel to use the [] style over time,
please don't move backwards on this. There are loads of commits by
Gustavo in the tree that show this work.
