net/mlx5: Disable SRIOV before PF removal

Browse source

Virtual functions depend on physical function for device access (for example
firmware host PAGE management), so make sure to disable SR-IOV once PF is gone.

This will prevent also the below warning if PF has gone before disabling SR-IOV.
"driver left SR-IOV enabled after remove"

Next patch from this series will rely on that when the VF may need to
access safely the PF 'driver data'.
