[MTHCA] 1. bugfix: gid lookup use wrong port number;
2. prints improvement to fit WPP;
3. ib_device_attr dont include specific Mellanox data;
4. added mechanism, providing the work with memfree devices in blocking mode, which requires transition a completion event from KVP to UVP.

The mechanism works as follows:
   upon create_cq:
      UVP allocates a doorbell record in UARC resident area;
      KVP stores the address of this record in the CQ object;
   upon completion:
      KVP posts event to this record (technically, increments sn - completion sequence number);
   upon arming the CQ:
      UVP consumes the event (technically, uses sn for numbering the next doorbell)
