Mark Johnston 9a7c2de364 realloc: Fix KASAN(9) shadow map updates
When copying from the old buffer to the new buffer, we don't know the
requested size of the old allocation, but only the size of the
allocation provided by UMA.  This value is "alloc".  Because the copy
may access bytes in the old allocation's red zone, we must mark the full
allocation valid in the shadow map.  Do so using the correct size.
