Input: remove unnecessary synchronize_rcu() call
There is no need to issue serialize_rcu() after adding a new handle to the list of handles associated with the device because new events will "see" the new handle in the list immediately. Remove it so we can boot a little bit faster. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
