add ifdef __sun__ for Solaris specific code

ENOTTY on direct I/O setup failure via directio(3C) is Solaris (ZFS)
specific (as also mentioned in ZoL commit[1]).

Linux and many others which support O_DIRECT never come here, but
others supporting direct I/O via OS specific way don't necessarily
have the same ENOTTY behavior or ZFS itself.

This commit brings back the original log before 42f1ee68 for others.
