Nathan Hjelm faf008f527 Fix bugs that were causing leaks in finalize.
This commit fixes leaks of bml endpoints in finalize. A summary of the
bugs/fixes is below.

 1) ompi_mpi_finalize used ompi_proc_all to get the list of procs but
    never released the reference to them (ompi_proc_all called
    OBJ_RETAIN on all the procs returned). When calling del_procs at
    finalize it should suffice to call ompi_proc_world which does not
    increment the reference count.

 2) del_procs is called BEFORE ompi_comm_finalize. This leaves the
    references to the procs from calling the pml_add_comm
    function. The fix is to reorder the calls to do omp_comm_finalize,
    del_procs, pml_finalize instead of del_procs, pml_finalize,
    ompi_comm_finalize.

 3) The check in del_procs in r2 checked for a reference count of
    1. This is incorrect. At this point there should be 2 references:
    1 from ompi_proc, and another from the add_procs. The fix is to
    change this check to look for a reference count of 22. This check
    makes me extremely uncomforable as nothing will call del_procs if
    the reference count of a procs is not 2 when del_procs is
    called. Maybe there should be an assert since this is a developer
    error IMHO.
