IB/cache: Add log messages for IB device state changes
Enhance visibility into IB device state transitions by adding log messages
to the kernel log (dmesg). Whenever an IB device changes state, a relevant
print will be printed, such as:
"mlx5_core 0000:08:00.0 mlx5_0: Port: 1 Link DOWN"
"mlx5_core 0000:08:00.0 rdmap8s0f0: Port: 2 Link ACTIVE"
