Jason A. Donenfeld c5373bd6e4 random: move initialization out of reseeding hot path
commit 68c9c8b192c6dae9be6278e98ee44029d5da2d31 upstream.

Initialization happens once -- by way of credit_init_bits() -- and then
it never happens again. Therefore, it doesn't need to be in
crng_reseed(), which is a hot path that is called multiple times. It
also doesn't make sense to have there, as initialization activity is
better associated with initialization routines.

After the prior commit, crng_reseed() now won't be called by multiple
concurrent callers, which means that we can safely move the
"finialize_init" logic into crng_init_bits() unconditionally.
