ZFS bug: was creating ZIL ignores vfs.zfs.min_auto_ashift, should be ZIL sets improper ashift with AHCI controllers

[Steven Hartland]

What does the following report for you when zdb on its own reports an 
incorrect ashift of 9?

zdb -l /dev/<your log device> | grep ashift

Here that reports the correct ashift, so I'm thinking that zdb on its 
own might be incorrectly reporting the ashift for some reason.
