Markus Elfring b934152170 drm/amd/powerplay: Delete a redundant memory setting in vega20_set_default_od8_setttings() 
The memory was set to zero already by a call of the function “kzalloc”.
Thus remove an extra call of the function “memset” for this purpose.

This issue was detected by using the Coccinelle software.
