PR libgfortran/65089
* io/format.h (free_format): New function to free memory
allocated for building format error messages.
* io/format.c (format_error): Add checks before freeing memory
to avoid potential segfaults and free formatting data when
needed on error conditions. Always allocate and NULL terminate
the string.
* io/transfer.c (st_read_done, st_write_done): Use new
free_format function to clean up memory allocations when done.
