was triggering an incorrect IRQ for tx-0 when the i226 is configured

This prevented XDP Zero-copy send functionality in such split IRQ
configurations.

The fix implements the correct logic for extracting q_vectors saved
during rx and tx ring allocation and utilizes flags provided by the
ndo_xsk_wakeup API to trigger the appropriate IRQ.
