dc66eee8f0 vhost_user_block: Ensure backing file consistency
Correctly implement the virtio specification by setting the writeback
field on the request based on the algorithm in the spec.

TEST=Boot with hypervisor-firmware with CH in verbose mode. See info
level messages saying cache mode is writethrough in firmware (no support
for flush or WCE). Once in the Linux kernel see messages that mode is
writeback.

e78e34b36a vhost_user_blk: Make DiskFile sharable across threads
The DiskFile will need to be shared across multiple threads when running
multiple queues across these threads. That's why it needs to be put
inside an Arc. The reason for the Mutex is because execute() expects a
mutable object implementing Read + Write + Seek. Unfortunately, this
create a contention point as the object needs to be locked from each
thread, reducing the performance gain we will get with multiple threads.

The need for an immutable object would solve this problem, and it will
be addressed later through follow up patches.
