IB/uverbs: Add CQ moderation capability to query_device

Browse source

The query_device function can now obtain the maximum values for
cq_max_count and cq_period, needed for CQ moderation.
cq_max_count is a 16 bits number that determines the number
of CQEs to accumulate before generating an event.
cq_period is a 16 bits number that determines the timeout in micro
seconds from the last event generated, upon which a new event will
be generated even if cq_max_count was not reached.
