drm/etnaviv: Delete unnecessary checks before two function calls 

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

The functions drm_gem_object_unreference_unlocked() and vunmap() perform
also input parameter validation.
Thus the tests around their calls are not needed.

This issue was detected by using the Coccinelle software.
