Only map front buffer if glamor acceleration is disabled (v2)

Otherwise the front buffer may not be accessible by the CPU, because Mesa
sets the AMDGPU_GEM_CREATE_NO_CPU_ACCESS flag for tiled buffers, because
accessing tiled buffers with the CPU makes little sense.

v2: Also handle Option "AccelMethod" "none"
