RDMA/counter: Allow manual mode configuration support
In manual mode a QP is bound to a counter manually. If counter is not
specified then a new one will be allocated.
Manual mode is enabled when user binds a QP, and disabled when the last
manually bound QP is unbound.
When auto-mode is turned off and there are counters left, manual mode is
enabled so that the user is able to access these counters.
