vlan: do not protect PCP write with the sysctl

Browse source 
pf will unconditionally "set prio", so this will fail if the
sysctl is off.  The sysctl, however, introduces a side-effect
so we would rather keep the default behaviour.  The allocation
slowdown is already taking place, so this in the worst case
only adds a list traversal / lookup.
