Fam Zheng 3482958383 virtio-blk: Remove op blocker for dataplane 
Block layer is prepared to unspecialize dataplane, an evidence is this
almost complete list of unblocked operations. It has all types except
two (actually three if DATAPLANE itself counts but blockdev.c makes sure
attaching twice is not possible): MIRROR_TARGET and BACKUP_TARGET.

blockdev-mirror refuses to start if target is attached, so the first is
not a problem.

By removing BACKUP_TARGET, blockdev-backup will become permissive to
write to a virtio-blk dataplane disk, but that is not worse than
non-dataplane given the latter is already possible. In either case,
blockdev.c always checks the target and source are on the same
AioContext, or bring them together if possible.
