Subject: [PATCH][next] drm/i915/gvt: Add missing breaks in switch statement

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

The switch statement is missing breaks for the cases of
GVT_FAILSAFE_INSUFFICIENT_RESOURCE and GVT_FAILSAFE_GUEST_ERR. Add them
in.

Detected by CoverityScan, CID#1462416 ("Missing break in switch")

Fixes: e011c6ce2b4f ("drm/i915/gvt: Add VM healthy check for workload_thread")
Fixes: a33fc7a0482a ("drm/i915/gvt: enter failsafe mode when guest requires more resources")
