    pvscsi: Explicitly mask out CTS_SAS_VALID_SPEED bit
    
    This driver prefers connection speed over sas port speed. On stable/13
    branch the stack-allocated CCB is not cleared thus the cam layer may
    report weird speed on boot.
    
    ```
    da0: <VMware Virtual disk 2.0> Fixed Direct Access SPC-4 SCSI device
    da0: 4294967.295MB/s transfers
    ```
    
    -current and stable/14 have the change [1] which clears stack-allocated
    CCB thus are not affected, but I want -current and stable/14 to have this
    fix in to reduce drift between branches.
