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()
