net/mlx5: Consider PCI domain in search for next dev

[ Upstream commit df7ddb2396cd162e64aaff9401be05e31e438961 ]

The PCI BDF is not unique. PCI domain must also be considered when
searching for the next physical device during lag setup. Example below:

mlx5_core 0000:01:00.0: MLX5E: StrdRq(1) RqSz(8) StrdSz(128) RxCqeCmprss(0)
mlx5_core 0000:01:00.1: MLX5E: StrdRq(1) RqSz(8) StrdSz(128) RxCqeCmprss(0)
mlx5_core 0001:01:00.0: MLX5E: StrdRq(1) RqSz(8) StrdSz(128) RxCqeCmprss(0)
mlx5_core 0001:01:00.1: MLX5E: StrdRq(1) RqSz(8) StrdSz(128) RxCqeCmprss(0)
