Add support for a common iWARP query port function, the new function
includes a common code that is used by the iWARP devices to update the
port attributes like max_mtu, active_mtu, state, and phys_state, the
function also includes a call for the driver-specific query_port callback
to query the device-specific port attributes.

Send and Receive completion is handled on a single CPU selected at
the time each Completion Queue is allocated. Typically this is when
an initiator instantiates an RDMA transport, or when a target
accepts an RDMA connection.
Some ULPs cannot open a connection per CPU to spread completion
workload across available CPUs and MSI vectors. For such ULPs,
provide an API that allows the RDMA core to select a completion
vector based on the device's complement of available comp_vecs.
ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted
to use the new API so that their completion workloads interfere less
with each other.
