patch 8.2.3216: Vim9: crash when using variable in a loop at script levelv8.2.3216

Problem:    Vim9: crash when using variable in a loop at script level.
Solution:   Do not clear the variable if a function was defined.
            Do not create a new entry in sn_var_vals every time.
            (closes #8628)
