[PATCH 02/10] IB/hfi1: Add tracing support for send with invalidate opcode

[Dennis Dalessandro <dennis.dalessandro-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

From: Jianxin Xiong <jianxin.xiong-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Enable trace generation for packets with the "Send Last with
Invalidate" and "Send Only with Invalidate" opcodes.
