[PATCH] archive-tar: make write_extended_header() void

[PATCH] archive-tar: make write_extended_header() void

[René Scharfe]

The function write_extended_header() only ever returns 0.  Simplify
it and its caller by dropping its return value, like we did with
write_global_extended_header() earlier.

Obviously correct, and much nicer to read. Thanks.
