Subject: [PATCH][drm-next] drm/vmwgfx: remove redundant return ret statement

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

The return statement is redundant as there is a return statement
immediately before it so we have dead code that can be removed.
Also remove the unused declaration of ret.

Detected by CoverityScan, CID#1473793 ("Structurally dead code")
