audit: do not needlessly take a lock in tty_audit_exit
We were doing spin_lock_irq and spin_unlock_irq. This is STOOPID.
If we were in interupt context we were already screwed and called
panic() in do_exit(). So the irq stuff is useless. Also, these values
can only be changed by receiving a netlink message from current. Since
we are in do_exit() clearly we aren't in the syscall sending the netlink
message to change these values. Thus, just read them and go with it.
