audit: handle a clean auditd shutdown with grace
When auditd stops cleanly it sets 'auditd_pid' to 0 with an AUDIT_SET message, in this case we should reset our backlog queues via the auditd_reset() function. This patch also adds a 'auditd_pid' check to the top of kauditd_send_unicast_skb() so we can fail quicker. Signed-off-by: Paul Moore <paul@paul-moore.com>

However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
