svn commit: r266522 - stable/9/sys/kern

  MFC r266426
  
  Slightly restructure the final loop in rman_reserve_resource_bound().
  Replace with the existing loop termination test with a similar
  condition from the nested "if" that may terminate the loop a bit
  sooner, but still not too early.   This condition can then be removed
  from the nested "if".  Relocate an operator to be style(9) compliant.
