    netfront: fix the support for disabling LRO at boot time

    The driver has a tunable hw.xn.enable_lro which is intended to control
    whether LRO is enabled. This is currently non-functional - even if its
    set to zero, the driver still requests LRO support from the backend.
    This change fixes the feature so that if enable_lro is set to zero, LRO
    no longer appears in the interface capabilities and LRO is not requested
    from the backend.
