Xiaolin Zhang 15e7f52a45 drm/i915/gvt: save RING_HEAD into vreg when vgpu switched out
Save RING_HEAD into vgpu reg when vgpu switched out and report
it's value back to guest.

v6: addressed comment for ring head wrap count support. (Zhenyu)
v5: ring head wrap count support.
v4: updated HEAD/TAIL with guest value, not host value. (Yan Zhao)
v3: save RING HEAD/TAIL vgpu reg in save_ring_hw_state. (Zhenyu Wang)
v2: save RING_TAIL as well during vgpu mmio switch to meet ring_is_idle
condition. (Fred Gao)
v1: based on input from Weinan. (Weinan Li)

[zhenyuw: Include this fix for possible future guest kernel that
would utilize RING_HEAD for hangcheck.]
