Make changes in server_mode() affect workers; fix a crash.

Without this fix, changes from client to bridge don't trigger
transition_affects_workers(), so we would never have actually
initialized the cpuworkers.

Fixes bug 23693.  Bugfix on 3bcdb26267502e0 0.2.6.3-alpha, which
fixed bug 14901 in the general case, but not on the case where
public_server_mode() did not change.
