Add disk_file::AsyncDiskFile trait implementation for
RawFileDiskSync with try_clone() and new_async_io() methods.
try_clone() duplicates the underlying file descriptor and
wraps it in a new RawFileDiskSync. new_async_io() creates a
RawFileSync (synchronous fallback) backend, wrapping errors
in BlockError instead of DiskFileError.
Add DiskFileError::Clone variant in async_io.rs for the
try_clone() error path.

The sync fallback path in process_queue_submit() hardcoded
VIRTIO_BLK_S_IOERR for all errors. This caused unsupported

code for each error variant.
