    xpp_fxloader: Don't try to load FPGA firmware twice
    
    When called from udev to load the FPGA firmware, make sure that this is
    not the event generated for the first end-point of the existing two, as
    we need to talk with the second one.
    
    This is probably better done in the udev rules, but will be slightly
    more complicated to apply only to the FPGA loading and not to USB
    firmware loading.
