Revert "drm/i915/gvt: set max priority for gvt context"

This reverts commit 11474e9091cf2002e948647fd9f63a7f027e488a.

There are issues which will block the host preemption before, instead of
disabling it use one workaround "setting max priority for gvt context"
to avoid the gvt context be preempted by the host. Now the issues have been
cleared, so revert this patch to enable host preemption.
