ip17xx: Initialize VLAN state upon reset

Browse Source 
Let VLAN state variables be initialized not only when the enable VLAN bit
is toggled, but also upon reset.

At this point, this should be a no-op, since the driver reads the current
hardware state before doing any modifications anyway, but I plan to keep
some state locally in the subsequent patches.
