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.
