rpma_peer_cfg_from_descriptor - create a peer cfg from the descriptor

rpma_peer_cfg_from_descriptor() creates a peer configuration object from the descriptor.

rpma_peer_cfg_from_descriptor() can fail with the following errors:

       •  RPMA_E_INVAL - desc or pcfg_ptr are NULL

       •  RPMA_E_NOMEM - out of memory

       The rpma_peer_cfg_from_descriptor() function returns 0 on success or a negative error  code  on  failure.
       rpma_peer_cfg_from_descriptor() does not set *pcfg_ptr value on failure.

       An  attacker  might  modify  the  serialized  remote  node  configuration  while it is transferred via an
       unsecured connection (e.g. rdma_cm private data), which might cause different remote  persistency  method
       selections.  The  most  dangerous situation is switching from the GPSPM mode to the APM one. Users should
       avoid using rpma_conn_get_private_data(3) and rpma_conn_req_get_private_data(3) API calls and they should
       utilize TLS/SSL connections to transfer all configuration data between peers instead.
