Off by one error sweeping vtable relocs

[Nick Clifton]

Hi Guys,

  I recently discovered an off by one error in
  elf_gc_propogate_vtable_entries_used().  The function computes 'n',
  the number of entries in the parent's vtable, but it then indexes
  whilst --n is non zero.  This will count one less than n iterations
  which is wrong.  The patch below fixes this.

Cheers
        Nick
