drm/amd/display: Fix compiler warnings on high compiler warning levels

Browse Source 
[why]
Enabling higher compiler warning levels results in many issues that can
be trivially resolved as well as some potentially critical issues.

[how]
Fix all compiler warnings found with various compilers and higher
warning levels.  Primarily, potentially uninitialized variables and
unreachable code.
