BUG/MINOR: errors: startup_logs_free: set global startup_logs ptr to NULL

ring_free() calls free() on the ring struct pointer, but startup_logs continues
to keep this address. So let's reset at the end startup_logs to NULL.
startup_logs is checked in print_message().

No need to backport this fix, as it's related to the latest master-worker
refactoring.
