RDMA/addr: Use time_after_eq() instead of time_after() in queue_req()
In queue_req(), use time_after_eq() instead of time_after()
for following reasons :
- Improves insert time if multiple entries with same time are
present.
- set_timeout need not be called if entry with same time
is added to the list (and that happens to be the entry
with the smallest time), saving atomic/locking operations.
- Earlier entries with same time are deleted first (fifo).
