random: avoid checking crng_ready() twice in random_init()
The current flow expands to:
if (crng_ready())
...
else if (...)
if (!crng_ready())
...
The second crng_ready() call is redundant, but can't so easily be
optimized out by the compiler.
This commit simplifies that to:
if (crng_ready()
...
else if (...)
...
