drm/amdgpu/vcn: reset fw_shared under SRIOV

Browse Source 
[ Upstream commit 3676f37a88432132bcff55a17dc48911239b6d98 ]

- The previous patch only considered the case for baremetal
  and is not applicable for SRIOV code path. We also need to
  init fw_share for SRIOV VF

Fixes: 928cd772e18f ("drm/amdgpu/vcn: reset fw_shared when VCPU buffers corrupted on vcn v4.0.3")
