[PATCH] drm/amdgpu: Senseless code and unnecessary memset

[Grigory Vasilyev]

Using memset on local arrays before exiting the function is pointless.
Compilator will remove this code. Also for local arrays is preferable to
use {0} instead of memset. Mistakes are often made when working with
memset.
