I've done some tests running a program that creates and binds(0) 90000 sockets.
The total running time, on average, is:
*  without this patch: 0.352 s
*  with the patch:       0.355 s

Also, recording this program with perf shows a small increase of 0.6%
for inet_csk_get_port
relative to inet_bind, after applying the patch.

So the performance is almost the same, even for such a large number of sockets.
