drm/amd/display: fix double memory allocation

Browse source

[Why & How]
when trying to fix a nullptr dereference on VMs,
accidentally doubly allocated memory for the non VM
case. removed the extra link_srv creation since
dc_construct_ctx is called in both VM and non VM cases
Also added a proper fail check for if kzalloc fails
