drm/amd/display: Check link_res->hpo_dp_link_enc before using it 



[WHAT & HOW]
Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res
without initializing hpo_dp_link_enc and it is necessary to check for
null before dereferencing.

This fixes 1 FORWARD_NULL issue reported by Coverity.
