George Bosilca 688a16ea78 A long time waiting patch. Get rid of the comm->c_pml_procs. It was (and that was
long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

This commit was SVN r11730.
