The scsipi_prevent() is called on close to release the drive and I suspect
the asynchronous erase just blocks the drive from executing and finishing
the prevent/allow command.
Now, that should only present an error (and keep the drive locked),
but the erase should complete somewhen.
But if the driver tries a bus reset in the timeout handling which also
resets the drive, this would abort the erase.
