RDMA/netdev: Use priv_destructor for netdev cleanup
Now that the unregister_netdev flow for IPoIB no longer relies on external
code we can now introduce the use of priv_destructor and
needs_free_netdev.
The rdma_netdev flow is switched to use the netdev common priv_destructor
instead of the special free_rdma_netdev and the IPOIB ULP adjusted:
- priv_destructor needs to switch to point to the ULP's destructor
which will then call the rdma_ndev's in the right order
- We need to be careful around the error unwind of register_netdev
as it sometimes calls priv_destructor on failure
- ULPs need to use ndo_init/uninit to ensure proper ordering
of failures around register_netdev
Switching to priv_destructor is a necessary pre-requisite to using
the rtnl new_link mechanism.
The VNIC user for rdma_netdev should also be revised, but that is left for
another patch.
