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

[Rahul Bhansali <rbhansali@marvell.com>]

From: Rakesh Kudurumalla <rkudurumalla@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.
