drm/amd/display: Remove redundant null checks

Browse Source 
The null checks for aconnector and aconnector->dc_link and
stream redundant as they were already dereferenced previously
as reported by Coverity; therefore the null checks are removed.

This fixes 4 REVERSE_INULL issues reported by Coverity.
