svn commit: r325453 - head/sys/powerpc/mpc85xx

Log:
  Fix an off-by-one error missed in the initial commit of this driver
  
  When the segment count is > 16 it spills into an 'indirect descriptor list',
  which immediately follows the main table, but the indirect list is entry 15, so
  needs to be skipped for the general list.
