net-next: ax88796: release platform device drvdata on probe error and module remove

Michael Schmitz · davem330 · commit 453da988785f · 2018-04-19T16:11:11.000-04:00
The net device struct pointer is stored as platform device drvdata on
module probe - clear the drvdata entry on probe fail there, as well as
when unloading the module.
