igc: Fix trigger of incorrect irq in igc_xsk_wakeup function

Browse source

This patch addresses the issue where the igc_xsk_wakeup function
was triggering an incorrect IRQ for tx-0 when the i226 is configured
with only 2 combined queues or in an environment with 2 active CPU cores.
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.

Fixes: fc9df2a0b5 ("igc: Enable RX via AF_XDP zero-copy")
Fixes: 15fd021bc4 ("igc: Add Tx hardware timestamp request for AF_XDP zero-copy packet")
