net/mlx5e: Fix error flow in representor failing to add vport rx rule

Browse Source 
[ Upstream commit 0a6b069cc60d68d33b4f6e7dd7f1adc3ec749766 ]

On representor init rx error flow the flow steering pointer is being
released so mlx5e_attach_netdev() doesn't have a valid fs pointer
in its error flow. Make sure the pointer is nullified when released
and add a check in mlx5e_fs_cleanup() to verify fs is not null
as representor cleanup callback would be called anyway.
