Gustavo A. R. Silva e90342e6d2 mm: memcontrol: use flex_array_size() helper in memcpy() 
Make use of the flex_array_size() helper to calculate the size of a
flexible array member within an enclosing structure.

This helper offers defense-in-depth against potential integer overflows,
while at the same time makes it explicitly clear that we are dealing with
a flexible array member.

Also, remove unnecessary braces.
