drm/i915/gvt: Fixed an issue in PS MMIO handlers
eeb071a 
When GVT-g guest tries to disable a scaler, it will write 0 to
PS_CTRL register. However, in such case, GVT-g PS MMIO handler will
not allow this value to be written to the HW, which will cause scaler
cannot be disabled.

This patch fixed the issue mentioned above.
