[PATCH] BSD accounting oops fix

oopses have been reported in do_acct_process(), with premption enabled, when
threaded applications are exitting.

It appears that we're racing with another thread which is nulling out
current->tty.  I think this race is still there after we moved current->tty
into current->signal->tty, so let's take the needed lock.
