Currently the QPC state in HW is modified inside the critical section of
spinlock but the ibv_qp state is modified outside. There will be a short
period when QPC state has been modified to err with ibv_qp state still
remaining RTS. WQEs during this period will still be post-send by RTS-state
ibv_qp but then dropped by err-state HW with no flush CQEs generated.
To fix this problem, the QPC state in HW and ibv_qp state should be both
modified to err inside the critical section of spinlock.
