drm/i915/gvt: Use sched_lock to protect gvt scheduler logic.
The scheduler lock(gvt->sched_lock) is used to protect gvt
scheduler logic, including the gvt scheduler structure(gvt->scheduler
and per vgpu schedule data(vgpu->sched_data, vgpu->sched_ctl).
v9:
- Change commit author since the patches are improved a lot compared
with original version.
Original author: Pei Zhang <pei.zhang@intel.com>
- Rebase to latest gvt-staging.
v8:
- Correct coding wqstyle.
- Rebase to latest gvt-staging.
v7:
- Remove gtt_lock since already proteced by gvt_lock and vgpu_lock.
v6:
- Rebase to latest gvt-staging.
v5:
- Rebase to latest gvt-staging.
v4:
- Rebase to latest gvt-staging.
v3: update to latest code base
