1. prov/shm: Add unmap_region function …

   This function is mainly for the niche case where on progress_connreq
   a peer is added to the map with its region needing to be mapped, and
   then after mapping it, it's discovered that the newly mapped peer's
   process died. In this case we need to unmap them and free any resources
   that were opened for communicating with them.
   
   Remove lock from map_to_region and unmap_region functions and require
   lock acquirement before calling those functions. This is necessary because
   on av removal path, map will be double locked if the functions also process
   locking the map. The map_to_region function is updated to mirror this
   policy.
