RELEASE UNIT releases the drive if it is currently reserved by the requesting initiator.
It is not an error to attempt to release the drive if it is not currently reserved to the requesting initiator. However, if it is
reserved by another initiator, the drive is not released.
3rdPty: The Third-Party release option for the RELEASE UNIT command allows an initiator to release a logical unit
that was previously reserved using the Third-Party reservation option.
If the 3rdPty bit is ZERO, then the Third-Party release option is not requested. If the 3rdPty bit is one, then the drive
is released, if the reservation was made using the Third-Party reservation option by the initiator that is requesting the
release and for the same SCSI device as specified in the Third-Party Device ID field.
