Theodore Ts'o dd1f723bf5 ext4: use prandom_u32() instead of get_random_bytes() ...

Many of the uses of get_random_bytes() do not actually need
cryptographically secure random numbers.  Replace those uses with a
call to prandom_u32(), which is faster and which doesn't consume
entropy from the /dev/random driver.
