timers/migration: Fix memory leak in tmigr_setup_groups() error path

Browse source

When the WARN_ON_ONCE(i >= tmigr_hierarchy_levels) assertion triggers,
the function returns -EINVAL without freeing the 'stack' memory allocated
via kzalloc_objs() at the beginning of the function.

Add kfree(stack) before returning to prevent the memory leak.
