Remove duplicate statements by using do-while loop instead of while loop.
- A;
- while (e) {
+ do {
A;
- }
+ } while (e);

Commit 496f2f93b1cc286f5a4f4f9acdc1e5314978683f ("random32: rename
random32 to prandom") renamed random32() and srandom32() to prandom_u32()
and prandom_seed() respectively.
net_random() and net_srandom() need to be redefined with prandom_* in
order to finish the naming transition.
While I'm at it, enclose macro argument of net_srandom() with parenthesis.
