vhost: cleanups and fixes for 3.10

Browse source 
Here are vhost cleanups and fixes by Asias He and myself.
 They affect both vhost-net and vhost-scsi devices.
 They also *depend* on both net-next and target-pending,
 where the net and target commits these changes depend on
 are already merged.
 So merging through the common vhost tree.
