From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch updates hw/scsi-bus.c to add PERSISTENT_RESERVE_OUT and PERSISTENT_RESERVE_IN
case in scsi_req_length() to extra the incoming buffer length into SCSIRequest->cmd.xfer,
and adds a second PERSISTENT_RESERVE_OUT case in scsi_req_xfer_mode() in order to properly
set SCSI_XFER_TO_DEV for WRITE data.
Tested with Linux KVM guests and Megasas 8708EM2 HBA emulation and TCM_Loop target ports.
