drm/amd/display: Skip on writeback when it's not applicable

Browse source

[ Upstream commit ecedd99a93 ]

[WHY]
dynamic memory safety error detector (KASAN) catches and generates error
messages "BUG: KASAN: slab-out-of-bounds" as writeback connector does not
support certain features which are not initialized.

[HOW]
Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.
