net/iavf: fix HW ring scan method selection

[ upstream commit 070ef4e ]

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".

Fixes: 0ed16e0 ("net/iavf: fix function pointer in multi-process")
