[Intel-gfx] [PATCH 1/9] drm/i915/dsb: Replace HAS_DSB check with dsb->cmd_buf check

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We may want to not use the DSB even if the platform has one.
So replace the HAS_DSB check in the _put() with a cmd_buf check
that will work in either case.
