The last commit was found when I created a XRC SRQ in
lock-free mode but failed to destroy it because of the
refcnt check added in the previous commit.
The failure was because the PAD was acquired through
ibv_srq->pd in destroy_srq(), while ibv_srq->pd wasn't
assigned when the SRQ was created by ibv_create_srq_ex().
So let's assign ibv_srq->pd in the common ibv_icmd_create_srq() ,
so that drivers can get the correct pd no matter
which api the SRQ is created by.

[ Upstream commit 65197a4 ]
Library expects ilog2 of psn_size while calculating the stride.
ilog32 returns log2(v) + 1 and the calculation fails since
the psn size is a power of 2 value. Fix by passing psn_size - 1.

When HW is in resetting stage, we could not poll back all the
expected work completions as the HW won't generate cqe anymore.
This patch allows driver to compose the expected wc instead of the HW
during resetting stage. Once the hardware finished resetting, we can
poll cq from hardware again.

Currently, there is a repeated judgement in check_qp_congest_type
whenever enable LDCP or HC3, the congest type flags all will be set
on LDCP.
This patch fixes this bug and replace a corrupt patch--0077, which
has a change that directly acts on patch but not code. This act
will disrupt the patch format.

Currently, if compiler does not support SVE, hns_roce_sve_write512() will
be a empty function, which means that this doorbell will be missed when
HNS_ROCE_QP_CAP_SVE_DIRECT_WQE is set in qp flag.
This patch ensures that driver will at least generate the DB regardless
of whether SVE DWQE is supported or not.
