Matias A Cabral 644641d06f PSM and PSM2 MTLs check on the max message size allowed by API.
OMPI send and receive mesages use size_t for the lenght while PSM and PSM2
psm(2)mq_send/receive use uint32_t. Type size_t is 64 bits in 64 bits arch.
Therefore, this patch adds a sanity check on the lenght of the message
and fails gracefully.
