net: dsa: remove trans argument from vlan ops

The DSA switch VLAN ops pass the switchdev_trans structure down to the
drivers, but no one is using them and they aren't supposed to anyway.

Remove the trans argument from VLAN prepare and add operations.

At the same time, fix the following checkpatch warning:
