22de5d77('Use ENOTSUP if OS doesn't support blkdev page cache invalidation')
changed errno values being used on supported platforms to ENOTSUP,
and also log_info'd it via strerror(), but strerror() isn't working
on some platform and instead prints irrelevant string.
Re: fio Windows Invalidate
http://www.spinics.net/lists/fio/msg06084.html
The logging of ENOTSUP could just be dropped since this isn't a real
failure, as many platforms either don't have the idea of invalidating
blkdev's page cache mapping, or use chrdev for block devices.
