Retire zfs_autoimport_disable kmod option
Back in 2014 the zfs_autoimport_disable module option was added to
control whether the kmods should load the pool configs from the cache
file on module load.  The default value since that time has been for
the kernel to not process the cache file.

Detecting and importing pools during boot is now controlled outside
of the kmod on both Linux and FreeBSD.  By all accounts this has been
working well and we can remove this dormant code on the kernel side.

The spa_config_load() function is has been moved to userspace, it is
now only used by libzpool.  Additionally, the spa_boot_init() hook
which was used by FreeBSD now looks to be used and was removed.
