[PATCH] iommu/amd: fix missing tag from dev_err message

From: Colin King
Date: Tue Jul 03 2018 - 02:40:16 EST

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently tag is being assigned but not used, it is missing from
the dev_err message, so add it in.

Cleans up clang warning:
warning: variable 'tag' set but not used [-Wunused-but-set-variable]

Fixes: e7f63ffc1bf1 ("iommu/amd: Update logging information for new event type")
Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx>

This is a re-working of an earlier incorrect fix that I posted
yesterday ("iommu/amd: remove redundant variable tag")
