[SCSI] Fix DVD burning issues.
Some pioneer DVDs are apparently returning odd "not ready" status
codes that the mid-layer doesn't recognise and so passes back to the
user as errors.
This patch overhauls our not-ready handling and adds transparent retries for:
format in progress
rebuild in progress
recalculation in progress
operation in progress
Long write in progress
self test in progress
The Pioneer was actually returning "long write in progress"
