Patch 7/14 common/cnxk: derive mbuf from CPT CQ in inline IRQ path
------------------------------------------------------------------
Error: NULL dereference at this commit.
- WQE_PTR_ANTI_REPLAY now calls work_cb() with sa = NULL and
cq_type NIX_INL_INB_CPT_CQ.
- At this commit, cn20k_eth_sec_sso_work_cb() still does
inb_priv = roc_nix_inl_ow_ipsec_inb_sa_sw_rsvd(args);
if (inb_priv->eth_sec && ...
which is PLT_PTR_ADD(NULL, HW_SZ) followed by a dereference.
- The guard only arrives in patch 8.
Squash 7 and 8, or move the guard first.
