drm/amd/display: ASSERT when failing to find index by plane/stream id
[WHY]
find_disp_cfg_idx_by_plane_id and find_disp_cfg_idx_by_stream_id returns
an array index and they return -1 when not found; however, -1 is not a
valid index number.
[HOW]
When this happens, call ASSERT(), and return a positive number (which is
fewer than callers' array size) instead.
This fixes 4 OVERRUN and 2 NEGATIVE_RETURNS issues reported by Coverity.
