drm/atomic: Initialize variables in drm_atomic_helper_async_check() to make gcc happy
drm_atomic_helper_async_check() declares the plane, old_plane_state and new_plane_state variables to iterate over all planes of the atomic state and make sure only one plane is enabled. Unfortunately gcc is not smart enough to figure out that the check on n_planes is enough to guarantee that plane, new_plane_state and old_plane_state are initialized. Explicitly initialize those variables to NULL to make gcc happy.
