Xin Long 4ef1a7cb08 ipv6: some fixes for ipv6_dev_find()

This patch is to do 3 things for ipv6_dev_find():

  As David A. noticed,

  - rt6_lookup() is not really needed. Different from __ip_dev_find(),
    ipv6_dev_find() doesn't have a compatibility problem, so remove it.

  As Hideaki suggested,

  - "valid" (non-tentative) check for the address is also needed.
    ipv6_chk_addr() calls ipv6_chk_addr_and_flags(), which will
    traverse the address hash list, but it's heavy to be called
    inside ipv6_dev_find(). This patch is to reuse the code of
    ipv6_chk_addr_and_flags() for ipv6_dev_find().

  - dev parameter is passed into ipv6_dev_find(), as link-local
    addresses from user space has sin6_scope_id set and the dev
    lookup needs it.
