In case of genl-family with parallel ops off, dumpif() callback

(genl: Allow concurrent genl callbacks.) changed this behaviour
where only first dumpit() op was called under genl-lock.
For subsequent dump, only nlk->cb_lock was taken.
Following patch fixes it by defining locked dumpit() and done()
callback which takes care of genl-locking.

As I've commented over in the other thread, I really think this is the
wrong thing to do. It was never the case that dumpit() was actually
locked under genl_lock(), and adding it doesn't really help anyone.
