Michael Heinz 89be953cfd REF6976 Silent failure of OMPI over OFI with large messages sizes
INTERNAL: STL-59403

The OFI (libfabric) MTL does not respect the maximum message size
parameter that OFI provides in the fi_info data.

This patch adds this missing max_msg_size field to the mca_ofi_module_t
structure and adds a length check to the low-level send routines.

(cherry-picked from commit 3aca4af548a3d781b6b52f89f4d6c7e66d379609)
