[Alexander Motin]

Author: mav

New Revision: 315082
URL: https://svnweb.freebsd.org/changeset/base/315082

Log:
  Allow XPT_GDEV_STATS for UNCONFIGURED devices.
  
  Queue statistics has nothing to do with presence or absence of INQUIRY
  data, etc.  Target mode devices are never configured, but have queues.
  
  MFC after:	2 weeks
