A few improvements to the worm driver.

- remove all calls to scsi_stop_unit(). Some drives refuse commands when
  stopped. This will fix the 'device not configured' message which was
  cleared after opening/closing the tray.
- Never set the logical block address in the scsi_cmd struct when writing.
  The computation was bogus for block sizes not a multiple of DEV_BSIZE.
  (the bug is still there in the READ case)
- reset the block size to the 2048 bytes in finalize_track() track to avoid
  an error when mounting a disk after an audio write.
- remove the WORMIOCQUIRKSELECT ioctl. Quirks are now recorded at probe time
  (see scsiconf.c)
- change and expand the argument to the WORMIOCPREPTRACK ioctl. It now possible
  to select more track options (copy bits, ISRC codes, track type,
  track number)
- add an error handler to catch false errors (warnings in fact) and record
  the error type.
- add an ioctl call (WORMIOERROR) to get more information on the nature of the
  error when a command or a write failed.
- add an ioctl call (WORMIOCFINISHTRACK) to finalize a track without closing
  the device (closing the device still finalize the track if the command was
  not performed)
