Gustavo A. R. Silva 9118796dfa wifi: mac80211: Add __counted_by for struct ieee802_11_elems and use struct_size() 
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure including, of course, the flexible-array member.

This code was found with the help of Coccinelle, and audited and
fixed manually.
