Nathan Hjelm 8df9b1d40d mtl/psm: add support for dynamic add_procs
Add an accessor for the proc_endpoints[OMPI_PROC_ENDPOINT_TAG_MTL]
member of the ompi_proc_t structure. This accessort calls add_procs
with the ompi_proc_t if the member is NULL. Tested on an infinipath
system with InfiniPath_QLE7340 HCAs.
