net: mana: Fix possible double free in error handling path

Browse Source 
[ Upstream commit 1864b8224195d0e43ddb92a8151f54f6562090cc ]

When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function adev_release
calls kfree(madev). We shouldn't call kfree(madev) again
in the error handling path. Set 'madev' to NULL.
