[PATCH] IPV6 debug printk error and missing release in error path

[Stephen Hemminger <shemminger@xxxxxxxx>]

A couple of small fixes for IPV6 network discovery:
  * A NPRINTK2 in ndisc_parse_options would not compile if ND_DEBUG level was 
up to 3
  * missing dst_release in ndisc_send_rs error path if skb_alloc fails.
