node_device_conf: Avoid memleak in virNodeDeviceGetPCIVPDDynamicCap()
    
    The virNodeDeviceGetPCIVPDDynamicCap() function is called from
    virNodeDeviceGetPCIDynamicCaps() and therefore has to be a wee
    bit more clever about adding VPD capability. Namely, it has to
    remove the old one before adding a new one. This is how other
    functions called from virNodeDeviceGetPCIDynamicCaps() behave
    as well.
