BUG/MEDIUM: threads/vars: Fix deadlock in register_name

In register_name, before locking the var_names array, we check the variable name
validity. So if we try to register an invalid or empty name, we need to return
without unlocking it (because it was never locked).

This patch must be backported in 1.8.
