storvsc: ring buffer failures may result in I/O freeze
commit e86fb5e8ab95f10ec5f2e9430119d5d35020c951 upstream.
When ring buffer returns an error indicating retry, storvsc may not
return a proper error code to SCSI when bounce buffer is not used.
This has introduced I/O freeze on RAID running atop storvsc devices.
This patch fixes it by always returning a proper error code.
