[PATCH 4.14 004/167] IB/qib: Fix comparison error with qperf compare/swap test

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxx>

commit 87b3524cb5058fdc7c2afdb92bdb2e079661ddc4 upstream.

This failure exists with qib:

ver_rc_compare_swap:
mismatch, sequence 2, expected 123456789abcdef, got 0

The request builder was using the incorrect inlines to
build the request header resulting in incorrect data
in the atomic header.

Fix by using the appropriate inlines to create the request.

Fixes: 261a4351844b ("IB/qib,IB/hfi: Use core common header file")
