IB/mlx4: Potential buffer overflow in _mlx4_set_path()
Smatch complains about this code:
drivers/infiniband/hw/mlx4/qp.c:1827 _mlx4_set_path()
error: buffer overflow 'dev->dev->caps.gid_table_len' 3 <= 255
The mlx4_ib_gid_index_to_real_index() does check that "port" is within
bounds, but we don't check the return value for errors. It seems simple
enough to add a check for that.
