[PATCH 07/10] drm/i915/frontbuffer: Extract intel_frontbuffer_ref()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

I want to hide the kref from the high level frontbuffer code.
To that end abstract the kref_get() in intel_frontbuffer_queue_flush()
(which is the only high level function that needs this) as a new
intel_frontbuffer_ref().
