Subject: net: thunder: Check for driver data in nicvf_remove()

From: Pavel Fedin <[email protected]>

[ Upstream commit 7750130d93decff06120df0d8ea024ff8a038a21 ]

In some cases the crash is caused by nicvf_remove() being called from outside. For example, if we try to feed the device to vfio after the probe has failed for some reason. So, move the check to better place.
