[ Upstream commit 31ac93386d135a6c96de9c8bab406f5ccabf5a4d ]

The error flow of mlx5e_create_netdev calls the cleanup call of the given profile without checking if it exists, fix that.

Currently the VF reps don't register that callback and we crash if getting into error -- can be reproduced by the user doing ctrl^C while attempting to change the sriov mode from legacy to switchdev.
