net/mlx5e: Avoid doing a cleanup call if the profile doesn't have it

Browse source

[ Upstream commit 31ac93386d ]

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.
