Description

The DSL Pool Configuration lock should be held when calling dsl_prop_register().

See comments here:

https://github.com/zfsonlinux/zfs/blob/master/module/zfs/dsl_pool.c#L947

and assertion here:

https://github.com/zfsonlinux/zfs/blob/master/module/zfs/dsl_prop.c#L238

Therefore osd_zfs will panic on mount if using a debug build of ZFS.
