Subject: drm/i915/gvt: Fix gvt scheduler interval time
From: Zhenyu Wang <[email protected]>
commit 2958b9013fcbabeeba221161d0712f5259f1e15d upstream.
Fix to correctly assign 1ms for gvt scheduler interval time, as previous code using HZ is pretty broken. And use no delay for start gvt scheduler function.
