drm/amd/amdgpu: fixing read wrong pf2vf data in SRIOV
[Why]
This fixes 892deb48269c ("drm/amdgpu: Separate vf2pf work item init from virt data exchange").
we should read pf2vf data based at mman.fw_vram_usage_va after gmc
sw_init. commit 892deb48269c breaks this logic.
[How]
calling amdgpu_virt_exchange_data in amdgpu_virt_init_data_exchange to
set the right base in the right sequence.
v2:
call amdgpu_virt_init_data_exchange after gmc sw_init to make data
exchange workqueue run
v3:
clean up the code logic
v4:
add some comment and make the code more readable
