svn commit: r218053 - projects/graid/head/sys/geom/raid

Log:
  Kill bio leak in the normal I/O path. Now we can survive the
  raid_rebuild_test.sh without leaking anything.  Before, we'd leak 40k
  bio when testing on a 200MB volume each time the test is run.
  
  # I haven't looked at tr_raid0.c to see if that's affected also.
