qcacld-3.0: Remove unnecessary net_device validation

Currently net_device is being validated inside the
hdd_for_each_adapter_dev_held_safe loop. This is not required as
hdd_for_each_adapter_dev_held_safe will hold the reference for
net_device and prevent it from being deleted. So net_device validation
is not required inside hdd_for_each_adapter_dev_held_safe loop.
