net/cnxk: fix inline device RQ tag mask

[ upstream commit 82529cf ]

Fix inline device RQ  tagmask to get packets with receive errors
as type ETHDEV packets to callback handler so that packet buffers
can get freed. Currently only IPsec denied packets get the right
tag mask.

Fixes: ee48f71 ("common/cnxk: support NIX inline inbound and outbound setup")
