$NetBSD: patch-src_third__party_wiredtiger_src_os__posix_os__fs.c,v 1.2 2020/03/24 14:34:06 adam Exp $

The fdatasync call is specified by POSIX, and the definition has changed:
  https://pubs.opengroup.org/onlinepubs/009695399/functions/fdatasync.html
  https://pubs.opengroup.org/onlinepubs/9699919799/functions/fdatasync.html  

NetBSD's fdatasync follows the earlier specification.  For now, simply avoid
crashing on EBADF, at the possible expense of sync safety.

\todo Change NetBSD to follow the current standard.
