RDMA/cm: Spurious WARNING triggered in cm_destroy_id()
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: 67b3c8dceac6 ("RDMA/cm: Make sure the cm_id is in the IB_CM_IDLE state in destroy")
