New Revision: 255973
URL: http://svnweb.freebsd.org/changeset/base/255973

Log:
  Fixed kernel crash when running devinfo
  
  When calling to ib_uverbs_cleanup_ucontext, there is a call to
  mutex_lock of xrcd_table_mutex, which was not initialized.
  Added missing initialization for xrcd_table_mutex.
