fix typo/thinko in get_random_bytes()
commit bd29e568a4cb6465f6e5ec7c1c1f3ae7d99cbec1 upstream.
If there is an architecture-specific random number generator we use it
to acquire randomness one "long" at a time. We should put these random
words into consecutive words in the result buffer - not just overwrite
the first word again and again.
