Use sizeof(*priv) instead of sizeof(struct stm32_rng_private), the
former makes renaming of struct stm32_rng_private easier if necessary,
as it removes one site where such rename has to happen. No functional
change.

IMHO the main upside is that it's easier to spot that the allocation
size is correct.
