[PATCH] drm/i915/gvt: fix memory leak of a cmd_entry struct on error exit path

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The error exit path when a duplicate is found does not kfree and cmd_entry
struct and hence there is a small memory leak.  Fix this by kfree'ing it.

Detected by CoverityScan, CID#1370198 ("Resource Leak")
