RDMA/mlx4: Read pkey table length instead of hardcoded value
commit ec78b3bd66bc9a015505df0ef0eb153d9e64b03b upstream.
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.
