random: Adjust the number of loops when initializing
commit 2dac8e54f988ab58525505d7ef982493374433c3 upstream.
When we are initializing using arch_get_random_long() we only need to
loop enough times to touch all the bytes in the buffer; using
poolwords for that does twice the number of operations necessary on a
64-bit machine, since in the random number generator code "word" means
32 bits.
