Free results of varobj_get_expression
varobj_get_expression returns an allocated string, which must be freed by the caller. gdb/ChangeLog: * mi-cmd-var.c (print_varobj): Free varobj_get_expression result. (mi_cmd_var_info_expression): Same. * varobj.c (varobj_get_expression): Mention in the comment that the result must by freed by the caller.
