When loading the ZFS kernel modules they should not populate the
spa namespace using the cache file. This behavior isn't consistent
with other Linux kernel modules and we need to move away from it.
Removing this makes the whole startup process predictable with four
basic steps which are driven by the init system.
1) modprobe
2) zpool import
3) zfs mount
4) zfs share
This change also helps lay the groundwork for eventually removing
the kobj_* compatibility code on the kernel side. It may need to
be preserved in userspace because libzfs_init() depends on it.
This is why the conditional must be wrapped with an #ifdef _KERNEL.
