RDMA/nes: Fix off-by-one bugs in reset_adapter_ne020() and init_serdes()
With a postfix increment, i is incremented one past 10K/5K before the loop ends, so the error messages will be displayed too soon if the test succeeds on the last iteration. Fix the comparisons to be > instead of >=. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
