When an admin enables audit at early boot via the "audit=1" kernel
command line, netlink send errors seen will cause the audit subsystem
to drop some records or return records to the queue. And all records
will be printed via printk() in the kauditd_hold_skb(), but actually
only the records that will be dropped need to be printed via printk().

When records are moved to the hold queue the system is in a bad state
so printing the record via printk() regardless of if the record is
able to be successfully queued or dropped is important. If this is
happening frequently on your system, this is likely a sign your system
is misconfigured.
