kasan: Fix a type conversion error
The current KASAN code can not find the following out-of-bounds bugs: char *ptr; ptr = kmalloc(8, GFP_KERNEL); memset(ptr+7, 0, 2); the cause of the problem is the type conversion error in *memory_is_poisoned_n* function. So this patch fix that. Signed-off-by:Wang Long <long.wanglong@huawei.com> Acked-by:
