In tegra_crtc_reset(), new memory is allocated with kzalloc(), but
no check is performed. Before calling __drm_atomic_helper_crtc_reset,
state should be checked to prevent possible null pointer dereference.
Fixes: b7e0b04ae4 ("drm/tegra: Convert to using __drm_atomic_helper_crtc_reset() for reset.")
