Revert "nasmlib/file.c: Windows _chsize_s() *returns* errno"

This reverts commit 55e51d9534a547c7bd4148d952b317884991078e.

First of all, _chsize_s() *does* set errno, even though it returns the
same value.  Second of all, all we look for is a zero return value
anyway, so there is no need for this wrapper.
