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.
