modesetting: NULL assignment for drmmode_set_target_scanout_target_cpu

Browse Source 
Commit 80e64dae: "modesetting: Implement PRIME syncing as a sink" originally was
supposed to have this line, but it was dropped as part of the merge process.

Foregoing the NULL assignment causes a ton of problems with dereferencing
uninitialized memory.
