RDMA/rtrs: Extend log message when a port fails

Add HCA name and port of this HCA.
This would help with analysing and debugging the logs.

The logs would looks something like this,

rtrs_server L2516: Handling event: port error (10).
		   HCA name: mlx4_0, port num: 2
rtrs_client L3326: Handling event: port error (10).
		   HCA name: mlx4_0, port num: 1
