Add struct virtqueue_ops back into the virtio core code to facilitate
the use of virtqueue implementations other than vrings. This allows
virtqueue implementations that use SMD drivers, USB drivers, or other
mechanisms for transport.
Add a new virtqueue operation, virtqueue_get_impl_size, to provide the
functionality of virtqueue_get_vring_size from the previous collapsed
implementation.
This commit partially reverts commit
7c5e9ed0c8.

Use the gpuaddr to determine whether memstore is being mapped in
mmap or a normal memory allocation is mapped instead of physical
address. gpuaddr of the memstore will always be unique but the
physaddr may be equal to the gpuaddr of another memory allocation
and that will cause the memory allocation to be mapped as memstore
which is wrong.

When the fault injection framework introduces an error to the data
block, the current code queries the SD card to find the number of
blocks actually programmed. This value would be as requested by the
generic block layer. So the entire request would be completed.
Say, request 0 is pulled from queue and submitted. When this is being
processed, request 1 is pulled from queue and prepared. Request 0
though is successful, fault-injection framework injects an error
and modifies the bytes_xferred variable to a random value less than
requested transfer. Request 1 is not processed and during the handling
of error, the SD card is queried for the actual bytes programmed. This
would be the correct value. Thus blk_end_request would complete
this request and the control would return to fetch request 2. In this
process, request 1 is not processed at all and the application waits
indefinitely for request 1 to be processed. No further requests are
issued to the queue.
This patch identifies, if the fault injection-framework has inserted an
error to this request and doesn't query the card and uses
bytes_xferred to complete the request.
