Handle some of the inquiry flags that have come into
usage as of SPC2r20. Specifically, handle the BQueue flag which will indicate that a device supports the Basic Queueing model (no Head of Queue or Ordered tags). When this flag is set, SID_CmdQueue is clear. This has causes FreeBSD to assume that the device did not support tagged operations. MFC after: 1 month
