[media] ddbridge: Replace vmalloc with vzalloc

vzalloc combines vmalloc and memset 0.

The Coccinelle semantic patch used to make this change is as follows:
@@
type T;
T *d;
expression e;
statement S;
@@

        d =
-            vmalloc
+            vzalloc
             (...);
        if (!d) S
-       memset(d, 0, sizeof(T));
