drm/hdlcd: Delete an unnecessary check before drm_fbdev_cma_hotplug_event() 

Author: Markus Elfring <elfring@users.sourceforge.net>

The drm_fbdev_cma_hotplug_event() function tests whether its argument
is NULL and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
