tty: audit: Remove tty_audit_buf reference counting
When tty_audit_exit() is called from do_exit(), the process is single-threaded. Since the tty_audit_buf is only shared by threads of a process, no other thread can be concurrently accessing the tty_audit_buf during or after tty_audit_exit(). Thus, no other thread can be holding an extra tty_audit_buf reference which would prevent tty_audit_exit() from freeing the tty_audit_buf. As that is the only purpose of the ref counting, remove the reference counting and free the tty_audit_buf directly.
