Vitaliy Shevtsov 56cddf71cc caif_virtio: fix wrong pointer check in cfv_probe() ...

[ Upstream commit a466fd7e9f ]

del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked
for NULL before calling it, not cfv->vdev. Also the current implementation
is redundant because the pointer cfv->vdev is dereferenced before it is
checked for NULL.

Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before
calling del_vqs().
