Log Message:
Some USB devices reports themselves as removable, but have no door and
so don't support the SCSI_PREVENT_ALLOW_MEDIUM_REMOVAL command.
When an "Illegal field in CDB" is reported for this command, mark the
device as non-removable (which is always true for USB keys from the SCSI
point of view), print a message and ignore the error.
For DIOCLOCK, return ENOTTY if the device is not removable instead of
trying a command which will fail.

Fix a problem reported by Hubert Feyrer for some USB umass devices, patch
tested by him.
