infiniband: make sure the src net is infiniband when create new link
When we create a new infiniband link with uninfiniband device, e.g. `ip link
add link em1 type ipoib pkey 0x8001`. We will get a NULL pointer dereference
cause other dev like Ethernet don't have struct ib_device.
The code path is:
rtnl_newlink
|-- ipoib_new_child_link
|-- __ipoib_vlan_add
|-- ipoib_set_dev_features
|-- ib_query_device
Fix this bug by make sure the src net is infiniband when create new link.
