Title: OMPI: btl openib: fix max registarable memory caluclation

- by default allow to register maximum possible (i.e 2 * total_memory)
memory. This beheviour can be turned off using mca parameter
"btl_openib_allow_max_memory_registration"

- In fallback case, use device specific parameters to calulate
memory limit.
