From: Patrisious Haddad <phaddad@xxxxxxxxxx>
Previously when we had a RAW QP, we bound a counter to it when it moved
to INIT state, using the counter context inside RQC.
But when we try to modify that counter later in RTS state we used
modify QP which tries to change the counter inside QPC instead of RQC.
Now we correctly modify the counter set_id inside of RQC instead of QPC
for the RAW QP.
Fixes: d14133dd4161 ("IB/mlx5: Support set qp counter")
