[ewg] [PATCH 03/10] attach cq to least cqs attached completion vector

[Vu Pham]

When the vector number passed to mlx4_cq_alloc is MLX4_LEAST_ATTACHED_VECTOR
the driver selects the completion vector that has the least CQ's attached
to it and attaches the CQ to the chosen vector.
IB_CQ_VECTOR_LEAST_ATTACHED is defined in rdma/ib_verbs.h, when mlx4_ib driv
recieves this cq vector number, it uses MLX4_LEAST_ATTACHED_VECTOR
