virtio: finalize features before using devicerel-1.16.1
Under the standard of Virtio 1.0, the initialization process of the
device must first write sub-features back to device before
using device, such as finding vqs.
There are four places using vp_find_vq().
1. virtio-blk.pci: put the code of finalizing features in front of using device
2. virtio-blk.mmio: put the code of finalizing features in front of using device
3. virtio-scsi.pci: is ok
4. virtio-scsi.mmio: add the code of finalizing features before vp_find_vq()
