[SCSI] mpt2sas: Fix device removal handshake for zoned devices
When zoning end devices, the driver is not sending device removal handshake alogrithm to firmware. This results in controller firmware not sending sas topology add events the next time the device is added. The fix is the driver should be doing the device removal handshake even though the PHYSTATUS_VACANT bit is set in the PhyStatus of the event data. The current design is avoiding the handshake when the VACANT bit is set in the phy status.
