Andriy Gapon f66c1f6482 zfs module: perform cleanup during shutdown in addition to module unload
- move init and fini code into separate functions (like it is done upstream)
- invoke fini code via shutdown_post_sync event hook

This should make zfs close its underlying devices during shutdown,
which may be important for their drivers.
