From: Lasse Collin <[email protected]>
set_error_fn() has become a useless complication after the commit
c1e7c3ae59b065bf7ff24a05cb609b2f9e314db6 fixed the use of error()
in malloc(). Only decompress_unlzma.c had some use for it and that
was easy to change too.
This also gets rid of the static function pointer "error", which
should have been marked as __initdata.
