drm/amdgpu: fix sriov host flr handler
We send back the ready to reset message before we stop anything. This is
wrong. Move it to when we are actually ready for the FLR to happen.
In the current state since we take tens of seconds to stop everything,
it is very likely that host would give up waiting and reset the GPU
before we send ready, so it would be the same as before. But this gets
rid of the hack with reset_domain locking and also let us tell how slow
ready to reset actually is from the host. The ready to reset speed can
be improved later.
