    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.
