Subject: [PATCH 5.4 058/344] drm/nouveau/nouveau: fix incorrect sizeof on args.src an args.dst

From: Colin Ian King <colin.king@...onical.com>

[ Upstream commit f42e4b337b327b1336c978c4b5174990a25f68a0 ]

The sizeof is currently on args.src and args.dst and should be on
*args.src and *args.dst. Fortunately these sizes just so happen
to be the same size so it worked, however, this should be fixed
and it also cleans up static analysis warnings

Addresses-Coverity: ("sizeof not portable")
Fixes: f268307ec7c7 ("nouveau: simplify nouveau_dmem_migrate_vma")
