Clear spa_config_source when done with split

By default it's not possible to open a device already owned by an active vdev. It's necessary to make an exception to this for vdev split. The FreeBSD platform code will make an exception if spa_config_source is set to SPA_CONFIG_SRC_SPLIT. To avoid allowing this once the split is complete, set spa_config_source to SPA_CONFIG_SRC_NONE.
