InfiniBand/RDMA fixes for 3.3: 

- Fix a crash due to a regression (uninitialized refcnt) introduced in
    3.2 with XRC support.
  - Close race in how ucma reports events when connect fails.
  - Process vendor-specific MADs in mlx4 so that eg FDR-10 data rate works.
  - Fix regression in qib caused by over-aggressive PCIe tuning.
  - Other small fixes for hardware drivers (ipath, nes, qib).
