vlan: Respect IFCAP_LRO mask
vlan_capabilities(), used by the IFCAP ioctl, was not respecting the IFCAP_LRO bit if it was masked by the requestor. This prevented if_bridge(4) from automasking LRO with a message like: bridge0: can't disable some capabilities on em3.11: 0x400 This also prevented manually disabling LRO from any vlan interface.
