kfifo: fix sparse complaints
This patch fix complaints by the sparse tool when using kfifo_put() with non scalar types like structures (i.e. drivers/iio/industrialio-event.c). Casting a pointer to the value and read this pointer instead of directly casting the value will fix this. The generated code is equal.
