[PATCH] drm/amd/amdgpu: fixing read wrong pf2vf data in SRIOV

[Jingwen Chen]

[Why]
This fixes 35709bd76d229a51b0c571a768b741650ec47828.
we should read pf2vf data based at mman.fw_vram_usage_va after gmc
sw_init. patch 35709bd76 breaks this logic.

[How]
calling amdgpu_virt_exchange_data in amdgpu_virt_init_data_exchange to
set the right base in the right sequence.
