mpi_leave_pinned when multiple OpenIB HCA ports are found. Specifically, if mpi_leave_pinned == 1 and ultiple HCA ports are found, the MCA parameter btl_openib_max_btls is set to 1. If the MCA parameter btl_openib_warn_leave_pinned_multi_port is true, emit a warning that this happened (having an MCA parameter to control the warning allows users/sysadmins to turn it off instead of being nagged for every run). This commit was SVN r10521.
