That is the code that was removed. It was removed entirely. No error handling was added to replace it. I would hope it will error or pause elsewhere if there is not enough random data though.
This means that this particular piece of code could NEVER be hit because there is never a time that RAND_status() is going to return 0! i.e. This is unreachable code.
On top of that RAND_add() is a no-op that won't do anything, since there is no way to add "seed" to the PRNG ...
