ractor_wakeup was broken when compiled with USE_RUBY_DEBUG_LOG

The `ractor_wakeup` function takes an optional `th` argument, so it can be NULL.
There is a macro call to RUBY_DEBUG_LOG that dereferences `th` without checking
if it's NULL first. To fix this, we never dereference `th` in this macro call.
