it doesn't even do harm to netif_poll_disable() twice as far as I can see, as it merely 
calls test_and_set_bit(), which will instantly succeed on the first attempt if the bit 
was already set.

did this change actually fix it for you? I'm wondering if the netif_carrier_off might 
not be the culprit here...
