IB/core, opa_vnic, hfi1, mlx5: Properly free rdma_netdev
IPOIB is calling free_rdma_netdev even though alloc_rdma_netdev has
returned -EOPNOTSUPP.
Move free_rdma_netdev from ib_device structure to rdma_netdev structure
thus ensuring proper cleanup function is called for the rdma net device.
Fix the following trace:
ib0: Failed to modify QP to ERROR state
BUG: unable to handle kernel paging request at 0000000000001d20
