Andrew Wolfers 9df6d57b48 Remove cached DrmKmsPlan resuse 
This CL resolves visual artifacts caused when the DrmKmsPlan is
cached from ValidateDisplay and later used during PresentDisplay.
This change restores prior behavior where the plan is created and
cached during validate, but then recreated fresh during present.
