qcacmn: Check for IPV6 before checking DHCPv6

Browse Source 
Currently we are not checking whether the packet is a IPV6 packet when
checking for a DHCPv6 packet. This can be error prone if done for a IPV4
packet.
Check for IPv6 before checking for DHCPv6.
Add QDF_NBUF_CB_PACKET_TYPE_DHCPV6 packet type in qdf_nbuf_cb.
