[ Upstream commit c64e9710f9241e38a1c761ed1c1a30854784da66 ]
ucmd in hns_roce_create_qp_common() are not initialized. But it works fine
until new member sdb_addr is added to struct hns_roce_ib_create_qp.
If the user-mode driver uses an old version ABI, then the value of the new
member will be undefined after ib_copy_from_udata().
This patch fixes it by initialize this variable to 0. And the default value
of the new member sdb_addr will be 0 which is invalid.

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.
