patch 9.1.1851: memory leak in heredoc_get()

Browse Source 
Problem:  memory leak in heredoc_get()
Solution: Free "str" if list_append_string() fails
          (Lidong Yan).

In heredoc_get(), eval_all_expr_in_str() allocates a new string and
assign it to local variable "str". When list_append_string() failed
the memory pointed to by "str" leaks. Free "str" if list_append_string()
failed.
