Subject: net/mlx5: E-switch, Removed unused hwid
Patch-mainline: v5.4-rc1
Git-commit: ef2e4094e076858343ea1202046443f642a245cd
References: jsc#SLE-8464

Currently mlx5_eswitch_rep stores same hw ID for all representors.
However it is never used from this structure.
It is always used from mlx5_vport.

Hence, remove unused field.
