net, init: assert each network reachability is true by default

The default network reachability values are implicitly set
by this line in net.cpp:

static bool vfLimited[NET_MAX] GUARDED_BY(g_maplocalhost_mutex) = {};

This commit asserts that each network is reachable during
the first loop through them during bitcoind init.
