some kmalloc/memset ->kzalloc (tree wide)

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

Here is a short excerpt of the semantic patch performing
this transformation:

@@
type T2;
expression x;
identifier f,fld;

expression E1,E2;
expression e1,e2,e3,y;

- memset((T2)x,0,E1);

- kzalloc(E1 * E2,E3)
