qcacld-3.0: Release dev_hold before interface cleanup

Browse source 
hdd_for_each_adapter_dev_held_safe API takes dev_hold and
during cleanup of interface, dev is unregistered. So later
when dev_put is called, it results in illegal access to
unregistered dev.
Fix this issue by releasing dev_hold before interface cleanup.
