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.

If the specified send CQ and recv CQ are both
the same CQ, the QP node in SCQ is not deleted.
which causes a segfault to occur when recreating
the QP. Here fix it.

[ 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.
