scsi: mpi3mr: Successive VD delete and add causes FW fault
Upon Virtual disk removal, firmware sends device status change event
(Virtual disk remove event) and expects the driver to start device remove
handshake (by sending target reset and IOU control command to firmware).
However, the driver does not initiate the device remove handshake which
leads to the firmware fault.
