for sense code "Logical Unit Is in Process Of Becoming Ready", make
the sense code evaluation function return ERESTART with xs->error = XS_BUSY;
then higher up catch this case and drop into the scbusy tsleep code.
For exabyte 8500 units, this makes st opening reprobe repeatedly, rather
than fail with an EIO while the tape is being loaded.
