RDMA/counter: Allow manually bind QPs with different pids to same counter

In manual mode allow bind user QPs with different pids to same counter,
since this is allowed in auto mode.
Bind kernel QPs and user QPs to the same counter are not allowed.

Fixes: 1bd8e0a9d0fd ("RDMA/counter: Allow manual mode configuration support")
