Subject: mlx4: remove unnecessary pci_set_drvdata()
Patch-mainline: v4.14-rc1
Git-commit: e084a8b89c173d7b37e886b277b6d3e05669259a
References: bsc#1046300 FATE#322946

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not necessary to manually clear the
device driver data to NULL.
