drm/amdgpu: Fix for BO move issue
A user reported a bug on CAPE VERDE system where uvd_v3_1 IP component failed to initialize as there is an issue with BO move code from one memory to other. In function amdgpu_mem_visible() called by amdgpu_bo_move(), when there are no blocks to compare or if we have a single block then break the loop.
