ipv6: take care of disable_policy when restoring routes
When routes corresponding to addresses are restored by
fixup_permanent_addr(), the dst_nopolicy parameter was not set.
The typical use case is a user that configures an address on a down
interface and then put this interface up.
Let's take care of this flag in addrconf_f6i_alloc(), so that every callers
benefit ont it.
