Subject: [PATCH 2/3] Virtio: wait virtio device reset done.
The Virtio 1.0 driver performs subsequent negotiation operations
only after the device reset operation is complete.
Implement this in the VirtioScsiDxe and VirtioBlkDxe.

When the VirtioBlk device is initialized, the value of SegmentSizeMax
is obtained based on the feature capability. Then delivere the requests
based on the value of SegmentSizeMax.
