Subject: [PATCH AUTOSEL 6.6 26/47] pds_vdpa: set features order

From: Shannon Nelson <shannon.nelson@....com>

[ Upstream commit cefc9ba6aed48a3aa085888e3262ac2aa975714b ]

Fix up the order that the device and negotiated features
are checked to get a more reliable difference when things
get changed.
