ipv6: Clean up ipv6_select_ident() and ip6_fragment()
This patch changes the ipv6_select_ident() signature to return a fragment id instead of taking a whole frag_hdr as a param to only set the frag_hdr->identification. It also cleans up ip6_fragment() to obtain the fragment id at the beginning instead of using multiple "if" later to check fragment id has been generated or not.
