If the cm_id state is IB_CM_REP_SENT when cm_destroy_id() is called, it
calls cm_send_rej_locked().
In cm_send_rej_locked(), it calls cm_enter_timewait() and the state is
changed to IB_CM_TIMEWAIT.
Now back to cm_destroy_id(), it breaks from the switch statement, and the
next call is WARN_ON(cm_id->state != IB_CM_IDLE).
This triggers a spurious warning. Instead, the code should goto retest
after returning from cm_send_rej_locked() to move the state to IDLE.
Fixes: 67b3c8dcea ("RDMA/cm: Make sure the cm_id is in the IB_CM_IDLE state in destroy")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
