net/cnxk: fix OOP handling for inbound pkts

To handle OOP for inbound packet, processing
is done based on NIX_RX_REAS_F flag. However, for the
SKUs that does not support reassembly Inbound Out-Of-Place
processing test case fails because reassembly flag is not
updated in event mode. This patch fixes the same.

Fixes: 5e9e008 ("net/cnxk: support inline ingress out-of-place session")
