When a CDB has been received and is about to be submitted to the SCSI layer
via one of the ESP select commands, ensure that do_cmd is set to zero before
executing the command.
Otherwise a guest executing 2 valid CDBs in quick sequence can invoke the SCSI
.transfer_data callback again before do_cmd is set to zero by the callback
function triggering an assert at the start of esp_transfer_data().
