This commit is OpenBSD version of 1116dc04 in 2015.
This is exactly the same as the previous commit for NetBSD.
OpenBSD still has block device as a file type, thus it differs
from FreeBSD/DragonFlyBSD regarding FIO_HAVE_CHARDEV_SIZE.
Note that fio doesn't compile on OpenBSD 5.9 (hits lex error),
but this this commit should still be good since this function
alone compiles on OpenBSD.
