From: Tomohiro Kusumi <tkusumi@xxxxxxxxxx>
This lets platforms without dio (e.g. OpenBSD) fail with an explicit
message, otherwise they fail without a clue about dio even with
--debug=all enabled.
"if (!OS_O_DIRECT)" is needed so that only platforms without both
O_DIRECT and FIO_OS_DIRECTIO print this message if/when called.
