[PATCH v1] net/iavf: fix select wrong scan hw ring by rxdid

[Steve Yang]

When setup RX queue, the rxdid would be changed if it's
"IAVF_RXDID_LEGACY_0/1", that caused the scan hw ring used the wrong
function 'iavf_rx_scan_hw_ring_flex_rxd()'.

Ignore the rxdid changed when equals "IAVF_RXDID_LEGACY_0/1".
