[PATCH] [ipv6]: adjust inet6_exit() cleanup sequence against inet6_init()

[Joe Jin]

Hi,

This patch for adjust inet6_exit() to inverse sequence to inet6_init().

At ipv6_init, it first create proc_root/net/dev_snmp6 entry by call
ipv6_misc_proc_init(), then call addrconf_init() to create the corresponding
device entry at this directory, but at inet6_exit, ipv6_misc_proc_exit()
called first, then call addrconf_init().
