net: mana: fix use-after-free in add_adev() error path
If auxiliary_device_add() fails, add_adev() jumps to add_fail and calls auxiliary_device_uninit(adev).
The auxiliary device has its release callback set to adev_release(), which frees the containing struct mana_adev. Since adev is embedded in struct mana_adev, the subsequent fall-through to init_fail and access to adev->id may result in a use-after-free.
Fix this by saving the allocated auxiliary device id in a local variable before calling auxiliary_device_add(), and use that saved id in the cleanup path after auxiliary_device_uninit().
