igbvf: remove unused interrupt counter fields from struct igbvf_adapter
Remove `int_counter0` and `int_counter1` from struct igbvf_adapter since they are only incremented in interrupt handlers igbvf_intr_msix_rx() and igbvf_msix_other(), but never read or used anywhere in the driver. Note that igbvf_intr_msix_tx() does not have similar counter increments, suggesting that these were likely overlooked during development. Eliminate the fields and their unnecessary accesses in interrupt handlers.
