Subject: [PATCH] Revert "net: sit: fix memory leak in sit_init_net()"

This reverts commit 375d6d454a95ebacb9c6eb0b715da05a4458ffef which is
commit 07f12b26e21ab359261bf75cfcb424fdc7daeb6d upstream.

Unnecessarily calling free_netdev() from sit_init_net().
ipip6_dev_free() of 4.9.y called free_netdev(), so no need
to call again after ipip6_dev_free().
