Fixes #11841 PR #11307 introduced the invariant that at most one credit request between session proc and quorum queue proc can be in flight at any given time. This is not the case when rabbit_fifo_client re-sends credit requests on behalf of the session proc when the quorum queue leader changes. This commit therefore removes assertions which assumed only a single credit request to be in flight. This commit also removes field queue_flow_ctl.desired_credit since it is redundant to field client_flow_ctl.credit (cherry picked from commit ce915ae)
