[PATCH 07/14] common/cnxk: derive mbuf from CPT CQ in inline IRQ path

[Rahul Bhansali]

From: Rakesh Kudurumalla <rkudurumalla at marvell.com>

Populate mbuf from WQE_PTR_CPTR and CPTR_WQE_PTR completions, handle
WQE_PTR_ANTI_REPLAY and CPTR_ANTI_REPLAY, and pass the mbuf pointer
into the inline device work callback instead of a fixed non-NULL
sentinel.
