Mark Bloch ec78b3bd66 RDMA/mlx4: Read pkey table length instead of hardcoded value 
If the pkey_table is not available (which is the case when RoCE is not
supported), the cited commit caused a regression where mlx4_devices
without RoCE are not created.

Fix this by returning a pkey table length of zero in procedure
eth_link_query_port() if the pkey-table length reported by the device is
zero.
