drm/amd/display: No need for Null pointer check before kfree
kfree() & vfree() internally performs NULL check on the pointer handed
to it and take no action if it indeed is NULL. Hence there is no need
for a pre-check of the memory pointer before handing it to
kfree()/vfree().
Issue reported by ifnullfree.cocci Coccinelle semantic patch script.
