qcacld-3.0: Add null vdev check in logging config

Browse Source 
Currently, host driver takes vdev reference while sending coex
logging config to the target. If user issues logging config
command before creating vdev, then vdev will be null and
dereferencing it causes crash in driver.

To fix this, add null check for vdev just after taking reference.
