[LTP] [PATCH] lib: tlibio.c: Restore LIO_IO_SYNCV

[Cyril Hrubis]

There was a single case of "#ifndef CRAY" in all the "#ifdef CRAY"
macros that got removed accidentally. This patch restores that piece.

Fixes: fed3e3ee6399 ('lib/tlibio: Get rid of support for old UNIXes')
Reported-by: Avinesh Kumar <akumar@suse.de>
