[net-next-2.6 PATCH 1/3] ixgbe: Remove unneeded register writes in VF VLAN setup

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Greg Rose <gregory.v.rose@intel.com>

The driver is unnecessarily writing values to VLAN control registers.
These writes already done elsewhere and are superfluous here.
