[IPV6]: Remove circular dependency on if_inet6.h
net/if_inet6.h includes linux/ipv6.h which also tries to include
net/if_inet6.h. Since the latter only needs it for forward
declarations, we can fix this by adding the declarations.
A number of files are implicitly including net/if_inet6.h through
linux/ipv6.h. They also use net/ipv6.h so this patch includes
net/if_inet6.h there.
